Abstract

In this paper, a dual‐surface combined‐field integral equation (DS–CFIE) formulation is presented for computing electromagnetic scattering from perfectly conducting arbitrary three‐dimensional (3‐D) bodies. The formulation has the advantage that it does not suffer from the internal resonance problem associated with the closed cavity modes. Convergence is typically obtained in a few iterations, and the formulation is relatively insensitive to the location of the virtual surface. Numerical results are presented for the case of plane‐wave scattering from a conducting sphere and a cube to validate the present approach. © 2001 John Wiley & Sons, Inc.
