Abstract

In this paper time-domain physics optics (TDPO) method is extended to its iterative version (TDIPO) to consider the coupling effects between two regions, and the latter is employed to investigate electromagnetic scattering from three dimensional target half-buried by a two dimensional rough surface. The time-domain iterative physics optics could also be enhanced by time-domain equivalent edge current (TDEEC) to further determine the far-field characteristics of the combinative target with rough surface. The validity of presented method is verified by comparing the transient scattering results for some common targets with those obtained through TDPO and finite difference in time domain (FDTD). Then simulation of EM scattering from target on rough surface are carried out to test the availability of TDIPO.
