Research Areas

Our group has worked in many diverse areas within electromagnetics, antennas, and microwave engineering. Below are listed some brief descriptions of areas in which we made pioneering contributions. We also have presented exciting and comprehensive presentations at many IEEE sponsored conferences including the International Symposium on Antennas and Propagation and International Microwave Symposium (IMS). Below is a video presentation by Prof. Rahmat-Samii at a recent IMS conference highlighting our work in the areas of electromagnetics.
