Abstract

Abstract

When numerical methods are used to solve the inhomogeneous media problems, generally, the large coefficient matrixes are generated. This results in the shortage of memory or very long computing time. In this paper, the domain decomposition method is applied to three-dimensional inhomogeneous media imaging. By means of dividing the domain into a few subdomains and iteratively solving the small problems on these subdomains, the large problem can be efficiently solved. The iterative curve shows the fast convergence rate. The imaging results of some complex inhomogeneous media problems are given in this paper.
