Education
Prabhakar Pathak received his Ph.D degree from the Ohio State Univ., Columbus, Ohio, USA, in 1973. Currently he is a Professor Emeritus at the Ohio State Univ.
Research Interests
Professor Pathak's main area of research is in the development of uniform asymptotic theories (frequency and time domain) and hybrid methods for the analysis of electrically large electromagnetic(EM) antenna and scattering problems of engineering interest. He is regarded as a major contributor to the development of the uniform geometrical theory of diffraction (UTD). Presently, he is developing new UTD ray solutions, for predicting the performance of antennas near, on or embedded in thin material/metamaterial coated metallic surfaces. Recently his work has also been involved with the development of new and fast hybrid asymptotic/numerical methods for the analysis/design of very large conformal phased array antennas for airborne/spaceborne and other applications. In addition, he is working on the investigation and development of Gaussian Beam summation methods for a novel and efficient analysis of a class of large modern radiation and scattering problems; some of that work is applicable to the analysis/synthesis of very large spaceborne reflector antenna systems. Professor Pathak has presented many short courses and invited lectures both in the U.S. and abroad. He has chaired and organized many technical sessions at national and international conferences. He was invited to serve as an IEEE (Institute of Electrical and Electronics Engineers) Distinguished Lecturer from 1991 through 1993. He also served as the chair of the IEEE Antennas and Propagation Distinguished Lecturer Program during 1999-2005. Prior to 1993, he served as an Associate Editor of the IEEE Transactions on Antennas and Propagation for two consecutive terms. He has published over a hundred journal and conference papers, as well as authored/co-authored chapters for seven books. He received the 1996 Schelkunoff best paper award from the IEEE Transactions on Antennas and Propagation. He received the George Sinclair award in 1996 for his research contributions to the O.S.U. ElectroScience Laboratory, and the Lumley Research Award in 1990, 1994 and 1998 from the O.S.U. College of Engineering. In July 2000, Prof. Pathak was awarded the IEEE Third Millennium Medal from the Antennas and Propagation Society. He was elected an IEEE Fellow in 1986, and is an elected member of US Commission B of the International Union of Radio Science (URSI).
