Dr. Ezekiel Bahar's fields of research are electromagnetic and acoustic wave propagation in inhomogeneous, anisotropic media with irregular boundaries, and microwave theory and techniques. He has developed generalized transform techniques to obtain full wave solutions to problems of scattering and depolarization of radio waves in nonuniform layered structures, nanostructures, complex chiral and metamaterials. He has employed generalized characteristic vectors to solve propagation problems in inhomogeneous anisotropic media. His research is applied to remote sensing, detection, navigation and communication. He uses an optical polarimetric scatterometer, which measures scattered Stokes vectors, and scanning tunneling/atomic force microscopes, which provide precise ground truth data, to obtain experimentally validated scattering theories. He is currently working in the field of propagation in complex media with applicaitons in nanophotonics and detection and identification of biolgical and chemical threat agents.

Dr. Bahar is a Life Fellow of the Institute of Electrical and Electronics Engineers and a member of Commissions B, C, F and G of the International Union of Radio Science. He is a member of the IEEE Antennas and Propagation and the Microwave Theory and Technique Societies.
