Integral equation domain decomposition method for solving electromagnetic wave scattering from non-penetrable objects

摘要: The integral equation (IE) method is commonly used to model time-harmonic electromagnetic (EM) phenomena. One of the major challenges in its application arises solution resulting ill-conditioned matrix equations. Here, we introduce a new domain decomposition (DD) based iterative for IE problems. There are two ingredients proposed IE-DDM: (a) type non-overlapping DD and provides computationally efficient effective preconditioner dense from method; and, (b) presented very suitable dealing with multi-scale EM Each sub-domain has own characteristics length will be meshed independently others. Numerical results demonstrate superior performance IE-DDM.
