本文提出了一种带阻抗边界条件的非共形非重叠积分方程区域分解法（IE-DDM-IBC），用于模拟多尺度涂层目标的电磁散射。提出的IE-DDM-IBC将多尺度涂层物体分解为互不重叠的子域，使每个子域可以根据其几何特征独立划分网格。除了渲染灵活的网格生成，建议的IE-DDM-IBC还有利于推导出一个有效的预条件，显着加快迭代求解器的收敛。
This letter presents a nonconformal nonoverlapping integral equation domain decomposition method with impedance boundary condition (IE-DDM-IBC) to simulate electromagnetic scattering from multiscale coated objects. The proposed IE-DDM-IBC decomposes a multiscale coated object into nonoverlapping subdomains so that each subdomain can be independently meshed according to its geometrical feature. Besides rendering flexible mesh generation, the proposed IE-DDM-IBC also facilitates the derivation of an effective preconditioner that significantly accelerates the convergence of iterative solvers.
