Abstract

This paper describes a marching-on-in-time (MOT) algorithm for solving a time domain electric field integral equation pertinent to the analysis of transient scattering from perfect electrically conducting (PEC) surfaces that are excited by very low frequency pulses. The algorithm uses loop-star (LS) basis functions to describe the spatial dependence of the electric current on the scatterer; these functions are shown to be essential to the algorithm´s accuracy and convergence properties.
