Michael Thiel, a graduate student in electrical engineering, was recently informed that he took first place in the international SEMCAD X Student Research Award 2008. He earned this honor for his research, “Analysis of Human Backscattering in Buildings for Through-wall Radar Applications.”

Mr. Thiel presents a method for the detection and localization of humans moving inside buildings. In his paper, he describes an efficient and accurate method for the analysis of human backscattering to ultra-wideband near-field UHF radar systems. The method combines a full-wave analysis of a human body model with a PO-like indoor propagation code. This method allows the analysis of human backscattering within a realistic building environment.

Michael works with Prof. Kamal Sarabandi, and is a member of the Radiation Laboratory. He received the award at the 2009 IEEE Antennas & Propagation Symposium, held June 1-5, 2009 in Charleston, SC.


This award is sponsored by Schmid & Partner Engineering AG (SPEAG) “to recognize outstanding research in the field of numerical simulation of electromagnetic fields being done in universities and other academic institutions.”

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
