B06: Analytical, Numerical and Hybrid Methods in Electromagnetics

Tuesday, August 19  13:40-15:40,  Room #19

Session Chairs: Donald Wilton, Giuliano Manara, Prabhakar Pathak

This session will focus primarily on ray optical ( UTD/GTD), or wave optical (PO/PTD), or beam Optical (Gaussian beams and complex source beams) or numerical methods (MoM, FEM, FE-BI). These methods may also be used in some systematic form of an appropriately paired hybrid combination to solve a variety of electrically large, and also possibly complex, EM antenna and scattering problems that otherwise cannot be solved efficiently and in a tractable fashion by any of these methods when just used alone. Basically, each method will generally exhibit domains of applicability and domains where they fail or maybe even become intractable; thus, the main purpose of any hybridization is to overcome the limitations of any one approach by systematically combining it with one or more of the other appropriate methods, so that the resulting hybrid solution can remain valid over the entire domain of interest while being also relatively efficient for applications.
