TLDR
In this paper, a time domain E field integral equation is solved by a process of marching in time, eliminating the need for matrix inversion and yielding the smoothed impulse response of the target.Abstract:
The computation of transient electromagnetic scattering from open thin surfaces using a time domain E field integral equation is described. The integral equation is solved by a process of marching in time, eliminating the need for matrix inversion. A Gaussian incident pulse is used, avoiding discontinuities, and yielding the ‘smoothed impulse response’ of the target. Responses are plotted for several target shapes.read more

TL;DR: In this paper, a general method is presented to treat the instabilities which are frequently observed in the electromagnetic transient solutions using the marching-on-in-time method, which is applied to apply an finite impulse response (FIR) filter with a constant group delay during the course of marching in time.
