A Parallelized Domain Decomposition Method with Conformal PML for Solving Electromagnetic Scattering Problems

摘要：

The core of domain decomposition method (DDM) is that it decomposes the original problem domain into several non-overlapping sub-domains, and solves every sub-domain independently. Since every sub-domain is solved independently by use of direct methods, we make the DDM be a parallelized algorithm. The conformal perfectly matched layer (PML) is introduced to this method for the analysis of electromagnetic scattering problems. This PML is based on a locallydefined complex coordinate transformation which has no explicit dependence on the differential geometric characteristics of the PML-free space interface. The DDM formulation is modified when the interface locates in the PML. We illustrate the application of the proposed approach via several 3D electromagnetic scattering problems.
