Teraphysics Corporation: participate in the commercialization of the (1) Terahertz (THz) frequency, the last unexploited region of the electromagnetic spectrum and (2) the upper regions of the Millimeter Wave (MMW) frequency


MY NOTE: I am not advocating that anyone should or shouldn't make an  investment in this "offering". I came across this link,  on the internet, and since I've mentioned Teraphysics several times before, and have spoken to them in the past, I thought it would be of interest to some readers of this blog. Do your own due diligence before investing!

Teraphysics offers investors an opportunity to participate in the commercialization of the (1) Terahertz (THz) frequency, the last unexploited region of the electromagnetic spectrum and (2) the upper regions of the Millimeter Wave (MMW) frequency. Microwave and infrared, the frequencies that border these frequencies have led to multi-billion dollar industries.
Often referred to as the “Terahertz Gap,” the technology has not been brought to commercialization due to the absence of compact sources and amplifiers capable of generating sufficient power. THz is a platform technology that will open many market opportunities.
Teraphysics recently achieved a revolutionary advancement: The first suite of commercially viable high frequency devices capable of generating and amplifying power levels previously unattainable from solid state and laser enabled sources. Our revolutionary devices are the most powerful hand-held THz and MMW devices in existence. Teraphysics is the sole owner of the critical proprietary technology that bridges the “THz Gap”.
The initial target markets for Teraphysics is food processing and safety and wireless communications. THz’s unique ability to detect micro contaminants or foreign materials in a variety of different foodstuffs has led to a number of customer-driven, high value applications in food safety and processing. Teraphysics’ MMW technology provides the wireless industry with a killer E-band solution for backhaul and the daunting data transmission demands the wireless industry is faced with.
With these technologies, Teraphysics is closely collaborating with global leaders in multiple market verticals in the development and sale of THz and MMW products and applications. With its technology and key commercial relationships, Teraphysics’ goal is to create a vertically integrated entity that will dominate THz and MMW commercialization. There is no visible competition on the horizon.

Products / Services

Food Safety
The addressable market for Food Safety is $1.5B (5,000 production lines X $250K per unit). Teraphysics projects a market penetration rate of 17% (847 units) over a 5 year period. Terahertz’s unique ability to detect concealed contaminants or foreign materials in a variety of different foodstuffs has led to a number of customer-driven, high value applications in the food inspection market, including food safety and food processing. Customer-driven projects in these markets have demonstrated the unique benefits of the Company’s products, not achievable with current inspection technologies such as X-Ray, microwave or optical imaging. We recently entered into a long-term and very profitable relationship with one of the world’s largest food producers. They intend to share our technology with others in the industry which would allow us to penetrate the huge global food safety market.
Wireless
The addressable world market is $308B (approx. 1M macro cell towers worldwide of which 70% are targets in major metro areas; 700,000 X 8 radios per tower = 5.6M radio units X an average selling price of $55,000 = $308B). We project a penetration rate of less than 1% (8,000 units) over a 5 year period. Wireless data traffic has more than doubled in each of the last 6 years, and it is predicted to expand at an exponential rate for years to come. The International Wireless Consortium predicts wireless data traffic to increase 5000 fold by the year 2030, with expectations of 100B devices being placed into service over the next 10-15 years. Two-thirds of the growth will come from a massive densification of micro cells, and our MMW amplifiers will magnify spectrum reuse dramatically. This opportunity has all of the elements of a creative monopoly as outlined in Peter Thiel’s book Zero to One. Also worth noting, the manufacturing of our devices will be outsourced leading to a minimal capex.

New Research In Ohio Labs Brings Star Trek Technology To Life

UC Davis researchers work on their project, "Terahertz Interconnect, the Last Centimeter Data Link"(Photo: Flickr Commons)
http://wosu.org/2012/news/2014/06/09/star-trek-technology-becoming-reality-in-ohio-laboratories/

Ohio is emerging as a global center of research in a branch of physics that’s stymied scientists for decades. It’s called Terahertz radiation, a band of light waves with potential uses that range from detecting cancer to uncovering art forgeries.
For those familiar with the original Star Trek series, they would remember the tricorder. Spock or McCoy could point the tricorder at anything, and instantly know its chemical makeup, see hidden objects, or diagnose diseases. A replica tricorder sits in the office of Teraphysics founder and president Jerry Mearini. As a fan of all things retro, and a physicist and entrepreneur, Mearini was inspired by the tricorder’s pretend powers.
“And when we started working on Terahertz devices, the first thing that came to my mind is we’re building the world’s first Star Trek Tricorder,” Mearini said.
He says it may not be science fiction much longer.
New technologies
“We’re not building the tricorder itself, we’re building the engine that drives it,” Mearini said.
The engine is a credit-card sized, high-power Terahertz generator— technology that’s eluded scientists since the 1960s.
Light is a spectrum. On one end you have high-energy, high-frequency X-rays; on the other end, low frequency radio waves – like the ones your car antenna captures. In the middle of the spectrum is visible light that you see all around you. People have made use of practically every part of that spectrum in one way or another, except for one. The Terahertz frequencies.
T-rays, as they’re called, fall between the heavily utilized wavelengths of infrared radiation—think night vision goggles and microwaves.
The Terahertz gap
But the equally promising Terahertz range has up until now been relatively inaccessible through existing technologies.  It’s been called the Terahertz gap.
“I wouldn’t describe it as a gap, but it is the spectral region that’s had the least attention, the fewest man years applied to it,” said Frank De Lucia, a physics professor at Ohio State. De Lucia is a pioneer in the field of Terahertz research. “And I think there’s a lot more virgin territory to explore and a lot more virgin things to find simply because it’s not been worked on much as a function of time.  And part of the reason for that is that it’s been difficult and expensive to build sources.”
And De Lucia says the practical, portable Terahertz source that Jerry Mearini has created is a significant jump forward.
Mearini said the tiny gold and diamond Terahertz generator is based on decades-old technology married to today’s nano-fabrication techniques. It’s about half the size of a human hair.
“It’s a vacuum tube, but a very modern day vacuum tube,” Mearini said. “But not unlike the glass vacuum tubes that are in my guitar amp at home, just a much cooler one.”
It took Mearini and his team 10 years of long nights to get it to work.
A new breakthrough
Teraphysics announced the breakthrough last month.
“It’s a paradigm shift because it would enable a whole class of new experiments that have not been conducted to date, or have not been conducted well to date, because of the lack of power in that frequency region,” said Elliott Brown, an expert in Terahertz technology at Wright State University in Dayton.
Brown sees enormous potential for the Teraphysics’ device, especially in biomedical imaging. In his lab, he uses T-rays to detect skin cancer, to diagnose burns, and to analyze DNA.
At Teraphysics in Cleveland, Mearini sees the potential of his device to identify chemicals, even at a distance.
“The most interesting aspect of Terahertz is that, in that frequency range, you can unambiguously identify molecular species, because most molecular species in that frequency range exhibit what we refer to as resonant signatures,” Mearini said.
Uses include public safety
The Terahertz spectrum can also ‘see’ through clothing and paper packaging.  It’s being tested in next generation airport scanners to detect hidden objects, or even the chemical signature of bomb material. T-rays are being used to link computer systems through high bandwidth wireless, also in secure communications, and data transfer. Other uses include inspection of paint and coatings, even uncovering art forgeries.
“It’s this unique area within the electro-magnetic spectrum that shows so much promise for so many applications that has really been tapped until now,” Mearini said.
The list of potential uses for Terahertz devices sounds like science fiction, but one Cleveland company, and researchers across Ohio, may soon make them a reality.

Providing timely information through high data rate communications enhances the situational awareness of military units engaged in combat and can be vital to their safety and the success of their mission. Such high data rate communications systems require amplifiers with broad bandwidth and high power, which can be delivered by the compact helical traveling wave tubes (TWT), under development at Teraphysics Corporation of Cleveland, Ohio.

Providing timely information through high data rate communications enhances the situational awareness of military units engaged in combat and can be vital to their safety and the success of their mission. Such high data rate communications systems require amplifiers with broad bandwidth and high power, which can be delivered by the compact helical traveling wave tubes (TWT), under development at Teraphysics Corporation of Cleveland, Ohio.
On May 14, 2014, Teraphysics was awarded a Phase I Small Business Innovative Research contract from the Air Force Research Laboratory at Wright Patterson Air Force Base in Dayton, Ohio to develop a 100 Watt TWT amplifier operating over the 5 GHz of contiguous bandwidth from 71 to 76 GHz in the region of the electromagnetic spectrum, known as E-Band.
The Teraphysics amplifier achieves the demanding requirements of the Air Force by utilizing computer design techniques originated by the contract Principal Investigator, Dr. Carol Kory, Teraphysics Vice President for Technology Development, and by adopting microfabrication technology originally developed for other applications. The Teraphysics TWT achieves very wide bandwidth by using a helical slow wave circuit consisting of a miniature coil of gold wire supported by a thin diamond sheet. The result is an amplifier with nearly constant gain over the 5 GHz bandwidth. The Teraphysics TWT has the length and width of a credit card and weighs only one pound, approximately one tenth the size of a conventional device.
Teraphysics has previously developed helical devices for operation at 650 and 94 GHz. The development of the Teraphysics miniature helical TWT had previously been supported by contracts with NASA Jet Propulsion Laboratory (JPL), the Defense Advanced Research Projects Agency (DARPA), the Army Research Office (ARO), and the Air Force Office of Scientific Research (AFOSR). In addition to the military applications, the compact Teraphysics TWT is expected to have significant impact on satellite communications, communication links for unpiloted aircraft (drones), and in the backhaul of accumulated signals of wireless handheld devices to the main fiber optic telecommunications network.

Researchers at Teraphysics make breakthrough in terahertz technology


http://www.rdmag.com/news/2014/05/researchers-make-breakthrough-terahertz-technology

Culminating a ten-year development effort, Teraphysics Corp. scientists have demonstrated the emission of terahertz light by passing electron beams through a gold coil, smaller in diameter than a human hair, supported by a diamond structure. The detection of a terahertz signal provided proof of concept for Teraphysics’ suite of microfabricated vacuum electronic devices.
The terahertz frequency is the last unexploited region of the electromagnetic spectrum, and is often referred to as the “terahertz gap.” Scientists and researchers have recognized the technical attributes and economic potential of Terahertz for more than 50 years. However, the absence of economical, high energy light sources has been the major hurdle preventing broad commercial applications.
Teraphysics’ unique achievement introduces new materials coupled with modern micromachining (MEMs) techniques to miniaturize a vacuum electron device. As a result, the Teraphysics’ devices have evolved to a package that weighs only one pound with dimensions that are smaller than a credit card. Conventional vacuum devices are at least ten times larger and heavier. The ability to economically harness terahertz energy with a compact device positions Teraphysics as the first mover in the commercialization of the exciting “final frequency frontier.”
A Cleveland-based technology development organization, Teraphysics and its strategic partner TeraView, Ltd., based in the United Kingdom, stand at the disruptive edge of commercializing terahertz.
Unique terahertz capabilities include:
  • Non-ionizing radiation unlike x-ray, therefore safe for use on and around humans;
  • Early disease detection including cancer and Alzheimer’s;
  • 3-D imaging through clothing and most packaging materials to detect concealed explosives and contraband;
  • Quality assurance in mobile electronics, food safety, pharmaceutical and other manufacturing sectors;
  • Quality control of specialty coatings applications, such as automotive paints, pharmaceuticals and confections, solar panels and early corrosion detection;
  • Unambiguous identification of substances through molecular fingerprinting;
  • Non-invasive cosmetic wrinkle smoothing techniques; and
  • Enormous bandwidth and secure wireless communications (at least ten times faster than fiber).
Terahertz applications will be transformational across many sectors – that which scientists previously understood as inconceivable, is now possible, and practical in the very near future.  The history of technology consistently provides us with examples of today’s conveniences not even conceived of as recently as a few decades ago. The cycle will repeat itself many times with terahertz.

Focus on Teraphysics




My Note: One of the more interesting companies I have come across in the last 4 years following THz on this blog is Teraphysics. You might note the video at the top of the blog, which peaked my interest. After posting it last month Teraphysics removed it from the web. I wrote the company, and got them to publically share the video again, so I am also reposting it. The following are some small parts of the company webpage. I encourage you to take the time to check out the full webpage. I hope to get some exclusive comments and insights in the near future.

The First Commercially Viable THz Source

1. Sufficient Power (10’s mW) to provide
a. Spectroscopy from a safe standoff distance
b. Real time video rate imaging from a distance
c. Significant penetration depths
2. Compact (<3 lbs, < 5 inches3)
3. Broad, continuously tunable frequency range
Applications mentioned have not been exploited commercially -they have only been demonstrated in laboratory environments. This has become known as the THz gap. But Why does this gap exist? Because there are no potential commercially viable sources in existence except the Teraphysics devices we present here. What is a commercially viable source? A source that can meet the requirements for the applications we outlined, or a source providing 10s of mW’s of average power that is compact, and continuously tunable over a broad range of frequencies.

 Survey of Existing THz Sources

Existing THz sources are used primarily for research purposes due to such factors as maturity, cost, size, efficiency and low output power at room temperature. Thus, none of these competing sources have the potential to be commercially viable except the Teraphysics’ suite of sources.

Vacuum Electronics Serve As Terahertz Power Source




http://www.mwrf.com/Article/ArticleID/23810/23810.html
Capabilities have greatly advanced for vacuum-electronic-device (VED) sources of terahertz and near-terahertz coherent radiation—both continuous wave (CW) and pulsed sources. Quantum-theory models of some terahertz VEDs have been developed and used with some success. Yet all terahertz VEDs can be explained with purely classical models, which is the approach taken by the following group of researchers: John H. Booske from the University of Wisconsin; Richard J. Dobbs from CPI Canada; Colin D. Joye from the US Naval Research Laboratory; Carol L. Kory from Teraphysics, Inc.; George R. Neil with the Thomas Jefferson National Accelerator Facility; Gun-Sik Park with Seoul National University; Jaehun Park from Korea’s Pohang University of Science and Technology; and Richard J. Temkin from the Massachusetts Institute of Technology.
For high-power devices needing to generate high-power electron currents in particular, the vacuum is an ideal propagation medium. VEDs do have tradeoffs, though. These include the need for a three-dimensional (3D), vacuum-tight enclosure.
The researchers note that terahertz devices based on VED technology cover a total bandwidth exceeding 10.0 THz. Terahertz-device choices can be roughly broken down into three classes. Compact sources with high mobility include backwards-wave oscillators (BWOs). They range from 0.1 to 1.0 THz with 10T-3 through 103 W (CW and pulsed) output power. Another option is compact gyrotons with moderate mobility, which cover 0.1 to 1.0 THz with 10-3 through 106 W (CW and pulsed) output power. Stationary accelerator-based sources, including free electron lasers (FELs), range from 0.2 to 10.0 THz and beyond with 10 through 109 W (average and pulsed) output power. See “Vacuum Electronic High Power Terahertz Sources,” IEEE Transactions On Terahertz Science And Technology, Sept. 2011, p. 54.
