Abstract
We consider the electromagnetic scattering problem of an inhomogeneous obstacle. The methodology applied combines a volume finite element method with a boundary integral method. Both are numerically solved in an efficient way and coupled with a domain decomposition method. The main ingredients are: domain decomposition method with Després's transmission conditions and concentric subdomains, Després's integral equations, fast multipole method, and a parallel sparse direct solver. Numerical results on different inhomogeneity and complex geometries are presented. To cite this article: K. Mer-Nkonga et al., C. R. Physique 7 (2006).
