Hybrid JMCFIE-DDM for electromagnetic modeling of composite structures

摘要

In this paper, a hybrid domain decomposition method with electric and magnetic current combined-field integral equation (JMCFIE) is present for modeling electromagnetic scattering problems involving composite structures. The method first decomposes the original problem into several sub-domains according to its geometry and dielectric parameters. JMCFIE serves as the sub-domain solver in which a well-posed matrix system can be achieved. The Robin-type transmission conditions are used across the touching face of adjacent sub-domains, which enforces the continuity of both electric and magnetic field. The Inner-Outer iteration technique based on the krylov sub-space is developed to solve the final matrix system. Finally, the proposed method is validated with some numerical results.
