Rather than present the standard fare, let’s shake things up a bit and switch frequency bands. We will discuss propagation in the optical frequency bands by outlining an experiment that you can do in the comforts of your own home or office. The goal: to understand the concept of shape factors and why they are important in multipath radio (and even optical) wave propagation. [Read more…]
Test your electrical engineering IQ, as well as your knowledge of 20th-century display hardware, with this circuits-based cathode ray tube test question. This problem appeared on a Georgia Tech Electromagnetics Exam in 2003.

This collaboration with the Ghovanloo group studies small antennas placed within the mouth. These antennas connect to sensors and allow short-range communication with radios outside the body. These sensors retrieve information such as tongue position, which can be used to pilot a motorized wheelchair. Congratulations, Fanpeng and company!
In this video, the Georgia Tech students study switched DC sources on transmission lines as part of their time-domain transmission line series. This is useful for designers of high-speed logic circuit boards, among other things.
