For those that miss problems-of-the-day, the website menu contains an archival link to a collection of these postings. The casual website reader probably wants nothing to do with PotDs, but for the select few who cannot get enough of applied problems in electromagnetism … enjoy!
PotD: The First Sequencer Problem
Below is the first time-domain transmission line “sequencer problem” that appeared in 2003 to test student’s knowledge of terminations, charged lines, reactive elements, cascades, and various other circuit behaviors. Believed (incorrectly) by many students to have been invented by Prof. Durgin specifically for the sadistic torture of Georgia Tech ECE 3025 students, these problems do nicely encapsulate two weeks of time-domain transmission line material in one single exercise. If you need some help understanding the concept, this lengthy video sample problem might make a good starting point.

2017 in a Word Cloud
Do you want a snapshot of the group’s activities last year? Here is a word cloud with all of the group’s 2017 publications incorporated to give the scope of the work for the past year. Not surprisingly, our researchers like RFID, antennas, and the IEEE. It starts to get diverse after that, branching out into power, coding, encryption, and localization.

How to Terminate
Termination schemes on transmission lines … there are a lot more ways to suppress ringing on high-speed logic lines than simply sticking the right resistor on the end of the line. This video is part of the time-domain transmission line series that we use in GT electromagnetics.
