- Astronomy – THz can assist astronomers in scanning the universe. Telescopes based in space or even land-based telescopes assuming they are at very high altitudes or based in very dry locations to scan between 100 GHz and 1 THz frequencies for obtaining images from outer space.
- Internet of Things (IoT) – According to Cisco, annual global IP traffic will pass the zettabyte threshold by the end of 2016, and will reach 2 zettabytes per year by 2019. And busy hour internet traffic will reach 1.4 petabytes per second (Pbps) in 2019. Traffic from wireless and mobile devices will exceed traffic from wired devices by 2017. As the demand for higher data rates increases, so does the need for a higher frequency band for being able to transmit huge amounts of data to address consumers’ hunger for ever-increasing data usage.
- Chemical Fingerprinting – One of the first imaging applications using THz is chemical finger printing. With this application, we can scan over a range of frequencies, different materials or packages or objects and detect what is inside them without destroying the object or without having to open the packaging. THz could be used to detect illegal drugs hidden in packages or on people. Another use of chemical fingerprinting is detecting explosives or weapons on people, in cars or in packaging or in trash bins by the side of the road. The idea here is to source THz signal crossing a range of frequencies and look at the reflected signal coming from the object that can be used for detecting weapons and explosives and identifying their unique composition. So by looking at the signature of different materials you could tell whether SEMTEX, TNT, or RDX explosives hidden on a person or in a package.
- Medical Imaging –Unlike an x-ray, THz is non-ionizing and far less hazardous for imaging human tissue, flesh and even dental use. It provides a higher resolution than x-ray and gives the ability to tell the difference in soft tissues so it is a great early detection for cancer cells as well as detecting cavities and issues with enamel layers with human teeth.
