Abstract

An integral equation‐based overlapped domain decomposition method (IE‐ODDM) is presented for the analysis of three‐dimensional (3D) electromagnetic scattering problems. Compared with the forward and backward buffer region iterative method proposed by Brennan et al., the convergence of the IE‐ODDM is faster due to the edge‐effect of the current in each subdomain being effectively depressed. Moreover, the iterative sequence among the subdomains of IE‐ODDM is more flexible, which means that asynchronous iteration and even parallel computing are doable. Simulated RCS results of several convex and concave 3D conducting objects verify the speedup and validity of this method. © 2006 Wiley Periodicals, Inc.
