- Professor Emeritus, Electrical & Computer Engr.
Prabhakar Pathak received his PhD degree from The Ohio State University in 1973. Currently he is a professor emeritus at Ohio State.
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.
