Education Ron Marhefka received his BS EE in 1969 from Ohio University, his MSEE in 1971 and the Ph.D. in 1976, both from OSU. Since that time he has worked at ESL and reached the rank of Senior Research Scientist and Adjunct Professor. He is a Fellow of the IEEE Research Interests Dr. Marhefka is involved in the analysis of practical scattering and antenna problems. This has included developing high frequency asymptotic solutions such as the uniform geometrical theory of diffraction, hybrid solutions, and other scattering techniques. He has been applying these high frequency techniques to analyze the radiation patterns of and the coupling between antennas in a shipboard and other complex environments. Dr. Marhefka has also extended these techniques and developed new solutions for finding the radar cross section of complex scattering bodies. Portions of his work have been incorporated in well-known and widely distributed general purpose computer codes. In addition, he has recently worked on developing frequency selective surfaces and broad band antenna arrays.
