Hi guys! My name is David Gentry (if you haven’t read that already). Right now, I am completing my M.S. degree in Electrical Engineering at Oklahoma State University. I will graduate in December, 2010. I joined the REFTAS group because I really enjoy learning about electromagnetic fields. Plus, I would like to have a better understanding of how electromagnetic systems are designed and built as compared to doing a circuit design. Things that interest me are: to better understanding the time-domain form of Maxwell’s equations, the transient response of electromagnetic systems, and software that can simulate electromagnetic systems. My hobbies are coin collecting, watching Stargate SG-1 (the series), and playing videos games (whenever I have time). |
