A Robust Scheme for TD-MoM Analysis of Planar PEC Objects

摘要

A robust, fast and simple scheme for calculation of potential integrals that encountered singular terms in time domain integral equation (TDIE) for planar PEC scatterers in free space is presented. In this method singular terms of the potential integrals, like other terms, calculated numerically by selecting some points in the source and observation patches in TD-MoM solver. In fact this method cancelled dealing with the singularity of self-terms.
