In this work, we present a new and efficient numerical method to solve the coupled integral equations, derived utilizing the equivalence principle for arbitrarily shaped dielectric bodies, directly in the time domain. The solution method is based on the method of moments, and involves the triangular patch modeling of the arbitrary body in conjunction with the patch basis functions. Detailed mathematical steps along with representative numerical results are presented to illustrate the efficacy of this approach. ©1999 John Wiley & Sons, Inc.
