Reminder of One of GT’s Great EM Professors

Posted on Written by

Prof. Pete Rodrigue received his B.S. and M.S. degrees in physics from Louisiana State University and his Ph.D. in applied physics from Harvard University. From 1958 to 1968, he worked for the Sperry Microwave Electronics Company in Clearwater, Florida, where he conducted research on properties and microwave applications of ferrites and developed parametric amplifiers and microwave acoustic devices. In 1968, Dr. Rodrigue joined the School of Electrical Engineering at Georgia Tech at the rank of professor and was promoted to Regents’ Professor in 1977. He introduced new microwave courses for undergraduate and graduate students, as well as in continuing education programs.

Congratulations Tianchong Jiang!

Posted on Written by

Congratulations to Tianchong (Michael) Jiang for completing his MS thesis entitled, “Tri-band Object-Resistant Antenna Design.”  Tianchong performed an outstanding original design, build, and test for a triple-band ISM antenna.  Not only did the antenna function well at the target bands, but incorporated object resistance techniques developed at the GTPG.  The methodology will be valuable for designing future antennas in commercial wireless devices.

High-Voltage Plasma Effects on Antennas

Posted on Written by

In 2013, Marcin Morys put together an excellent study in channel measurement and modeling of coronating antennas in high-voltage environments.  In general, there was (and still is) a lack of understanding of high-voltage effects on antennas by a profession that wishes to proliferate “smart grid” sensors on power lines and high-voltage equipment.  Morys’ comprehensive study in theory and practical measurement was the most complete treatment of the otherwise neglected field of antennas at high voltage.  In particular, the effects of corona and both the noise processes and radiation alteration caused by these high-voltage plasmas proved to be one of the most original contributions of not only Morys’ work, but the lab in general.    Download the following set of notes on the subject of plasma antennas.
