Abstract :
A solution procedure to obtain the transient scattering by arbitrarily shaped conducting objects directly in the time-domain using the marching-on-in-time method is presented. The late-time oscillations are eliminated by a simple stabilization procedure which involves a 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
