Abstract

The multi-trace domain-decomposition surface integral equation (MT-DD-SIE) originally proposed to analyze electromagnetic scattering from dielectric composite objects is extended to efficiently account for perfect electrically conducting (PEC) bodies. This extension uses a special form of Robin transmission conditions (RTCs) on the surfaces of the PEC bodies to “couple them to the dielectric bodies. Rao-Wilton-Glisson (RWG)-based discretization of these RTCs, which are the only governing equations on PEC surfaces, yields a well-conditioned matrix block. Therefore, PEC bodies are accounted for within the MT-DD-SIE solver without negatively affecting the convergence of the iterative solution. The accuracy and the efficiency of this approach are demonstrated by numerical examples.
