Ellen o_Conner : The electromagnetics group here is one of the best in the country. All four professors, Drs. Jackson, Wilton, Williams and Long, are internationally recognized. I'm particularly interested in dielectric resonator antennas (DRAs), which were first proposed by Dr. Stuart Long. The heart of any wireless network is its antenna and DRAs offer many advantages. They are low profile, low-loss antennas suitable for high frequency applications. Dr. Long is a leading authority on the subject, so an opportunity to study under him was very exciting.
