Time domain scattering from open thin conducting surfaces

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.
