Transient scattering from three-dimensional arbitrarily shaped dielectric bodies

Abstract

A surface integral equation approach is utilized to calculate the transient scattering from arbitrarily shaped, three-dimensional dielectric bodies illuminated by an incident electromagnetic pulse. The surface of the dielectric body is discretized with triangular patches so that fairly arbitrarily shaped objects may be modeled. The Poggio–Miller–Chang–Harrington–Wu [ R. Mittra, Computer Techniques for Electromagnetics ( Pergamon, Oxford, 1973)] formulation, in conjunction with the marching-on-in-time method, is used to derive explicit expressions for the present-time currents as a function of the incident field and the past history. The late-time instabilities are suppressed by use of a simple averaging scheme. Finally, sample results showing various geometries are presented and are compared with other numerical techniques.
