对于复合导体和介质目标的电磁波散射问题,一个有效的积分方程求解器是必不可少的。本文提出了一种结合非共形、非重叠区域分解法(DDM)和电流/磁流组合场积分方程(JMCFIE)的增强预处理混合方法。它提供了一种灵活的方法来分解复杂的组合问题到容易解决的子域。为了防止非物理反射接触子域的面,罗宾型传输条件被用于子域的接触面。采用一种改进的预处理内外迭代格式,外迭代采用DDM作为整个系统的块Jacobi预处理器,内迭代采用基于多层快速多极子算法(MLFMA)最细层簇自相互作用的四分区块对角预处理器(4PBDP).在数值例子中,所提出的计划的效率。
For electromagnetic wave scattering by composite conductor and dielectric objects, an efficient integral equation solver is imperative. In this letter, An enhanced preconditioned hybrid approach combining a nonconformal, nonoverlapping domain decomposition method (DDM) and electric/magnetic current combined-field integral equation (JMCFIE) is proposed. It provided a flexible method to decompose the complex composite problem into easily solvable subdomains. To prevent unphysical reflections from the touching the face of the subdomain, Robin-type transmission conditions are used across the touching face of subdomains. An enhanced preconditioned inner-outer iteration scheme is employed in which DDM acts as a block Jacobi preconditioner for the whole system as the outer iteration, and a four-partition block-diagonal preconditioner (4PBDP) that is based on self-interactions of the finest level clusters of multilevel fast multipole algorithm (MLFMA) is further used in the inner iteration solution. In numerical examples, the efficiency of the proposed scheme is shown.
