On Tuesday, Zachary Silva successfully presented and defended his MS thesis entitled, “Optically Transparent Antennas for Multi-Modal Sensing.” The thesis is a remarkable survey and synthesis of transparent RF electronic materials and design principles. Zach currently works for Sandia National Labs and is planning to continue in the PhD program. Congratulations, Zach!
Our friend at the SPAN (Sensors and Processing Across Networks) Lab have recently moved to the University of Washington at St. Louis. Founded by Prof. Neal Patwari, the group originally started at the University of Utah. Check out their website here. The SPAN lab and GTPG have worked together on several memorable collaborations, including attachable sensor/antenna combos that can be stuck to the exterior of buildings and monitor interior movement.
Fun fact: the first research paper published by Prof. Patwari and the first research paper published by Prof. Durgin were … the same paper!
This article provides a derivation of the Rayleigh criterion for surface roughness. As a once-flat surface roughens, the specular reflected wave begins to degrade in power as some of it is scattered in different directions. The result is a predictable degradation that is a function of the rough surface statistics. The end result — the Rayleigh criterion — is used throughout science and engineering to describe everything from propagation off of building sides to the specifications for a satellite dish antenna.
