Abstract

In this paper, a hybrid MoM and PO method is proposed to speed up the computation time and reduce the memory requirement of a regular integral equation based MoM solver. It has been shown that in the frequency domain a MoM based integral equation solver when merged with a PO solution methodology can lead to an efficient and accurate solution methodology for the analysis of electrically large problems. In this paper, the same concept is extended to such a combination in the time domain for transient scattering analysis from large structures. Sample numerical results are presented to illustrate these improvements.
