Integral equation domain decomposition method for scattering from thin coating objects

In this paper, a novel non-conformal non-overlapping integral equation domain decomposition method with impedance boundary condition (IE-DDM-IBC) is presented to simulate the EM scattering from thin coating objects. By using the Robin transmission condition, the original object can be decomposed into several non-overlapping closed sub-domains, and each sub-domain can be meshed independently. It also provides an effective preconditioner to realize fast convergence for thin coating objects with multi-scale property.
