Abstract:

In this paper,the application of an integral equation domain decomposition method is discussed.Integral equation method can solve EM scattering problems precisely.The IE method is subjected to the Green Function,requiring dense and very complicated matrix solution.Domain decomposition method is an interactive method,which divides a big object into some sub-domains and solves each sub-domain to get the final answer.Each sub-domain's scattering wave is treated as a second incident wave to other sub-domains.Each of the sub-domains has its own characteristics and will be meshed independently,as a result of which it is very suitable for solving multi-scale problems.Numerical results compared with commercial software demonstrate the effectiveness of the method.

Key words: integral equation method;domain decomposition method;multi-scale object
