Time-domain electromagnetic scattering simulations on multicomputers

A series of bistatic radar cross sections of a perfectly conducting sphere over a frequency range were processed on one shared and three distributed memory computers. A comparative study was conducted for both the total field and the scattered field formulations. The accuracy criteria for the grid point density per wavelength and the placement of the truncated far-field boundary were also established for the present characteristic-based finite volume scheme. The numerical accuracy of all simulations has been validated with theoretical results. (C) 1996 Academic Press, Inc.
