Abstract

In this paper, we present a new formulation using the time‐domain electric‐field integral equation (TD–EFIE) to obtain a transient scattering response from arbitrarily shaped conducting bodies. The time derivative of the magnetic vector potential is approximated with a central finite difference, and the scalar potential is time averaged by dividing it into two terms. This approach with an implicit method using central‐difference results in accurate and stable transient scattering responses from conducting objects. Detailed mathematical steps are included, and several numerical results are presented. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 31: 429–435, 2001.
