My Note: Last week I got an interesting email from John Scales about the Mesoscopic Physics Lab at the Colorado School of Mines. I had never heard of Mesoscopics, and found a wealth of interesting information on the webpage(s). The following is just a sample.
Randy, saw your nice blog and thought you might be interested in some
the THz work going on in my lab. We have a fairly exotic sub-mm wave VNA and
have recently built a high power THz laser. We have a pulsed time-domain system
but we don't use it and will probably take it apart soon. We do a mix of
theory, computation and experiment.
Recent papers on my wiki.
Regards,
John

We specialize in the application of quasioptical (millimeter wave) and optical techniques for materials characterization as well as fundamental studies of wave propagation in disordered media. The latter presents a useful analog of quantum chaos. We study both natural materials, such as rocks, and artificial materials, such as photonic crystals and random dielectrics. We are also interested in the magnetic properties of metamaterials which could be exploited to create negative index materials at millimeter wave frequencies. As an example of an application, we are developing new types of nonlinear ultrasonic arrays and millimeter wave vibrometers for near-surface remote sensing (such as landmine detection).
What's the difference between terahertz and millimeter
waves?
waves?
Some current projects

- nonlinear acoustics/ultrasonics
- plasma generation of THz
- linear and nonlinear phased arrays
- millimeter wave vibrometry and remote sensing
