I'm a PhD student in Electrical Engineering at the University at Buffalo. Most of my research has been on composite right/left-handed (CRLH) structures and their applications: frequency-scanning antennas, reflectarrays, and integration with negative resistance reflection amplifiers to compensate for losses. This site serves as a repository of some professional stuff, as well as some personal projects.
