Analysis of electromagnetic scattering from complicated objects using nonconformal IE-DDM

This paper extends the integral equation domain decomposition method (IE-DDM) with Robin Transmission Condition (Robin TC) to the electromagnetic analysis of general objects of arbitrary shape, even for composite conducting-dielectric structures. Meanwhile, nonconformal mesh processing is formulated for the IE-DDM. The method is based on the CFIE-GCFIE integral equation formulation. First, we present the IE-DDM formulations for composite conducting-dielectric objects. Then, the nonconformal mesh processing is introduced into the IE-DDM. And last, the numerical results are also given to prove the validity of the present method.
