A stable procedure to calculate the transient scattering by conducting surfaces of arbitrary shape

In this paper, a solution procedure is presented to obtain the transient scattering by arbitrarily shaped conducting objects directly in the time-domain using the marching-on-in-time method. The late-time oscillations are eliminated by a simple stabilization procedure which involves negligible amount of extra computation. Numerical results for surface current density and far-scattered fields are given for various structures and compared with other methods.
