Hybrid Version of Method of Moments Computer Code: IBC3D

Abstract

IBC3D is a computer program used to calculate the electromagnetic scattering cross section and electric/magnetic surface currents for arbitrary three dimensional bodies coated with anisotropic lossy materials. An enhanced version of this code, developed by the Radar Division of the Naval Research Laboratory (NRL), is described here that allows one to generate a hybrid scattering solution by incorporating surface currents generated external to the IBC3D. The benefit derived from using the hybrid approach is gained by reducing the number of surface current unknowns required to produce a scattering cross section using numerically intensive computer codes such as IBC3D. When compared to the unmodified IBC3D solution for a 5-sided prism shaped object a 20 percent reduction in the number of electric surface current unknowns was obtained using the hybrid version of the code with minimal sacrifice in accuracy.
