Research

Dr. Wasylkiwskyj’s past research and industrial experience covers a broad spectrum of electromagnetics, including microwave components and techniques, phased array antennas, propagation and scattering, radar cross-section modeling as well as modeling of geophysical and oceanographic electromagnetic phenomena. In addition, he has extensive experience in ocean and structural acoustics with applications to active SONAR. His current research activities are primarily in numerical electromagnetics, mutual coupling in array antennas and algorithms for direction- of -arrival (DOA) estimation using array antennas and Emitter Range Estimation.
