Hybrid Finite Element Domain Decomposition Boundary Element Method for Analyzing Bi-Anisotropic Objects

This paper proposes a domain decomposition method (DDM) for hybrid finite element method (FEM) and boundary element method (BEM) to solve arbitrary three dimensional (3D) bianisotropic objects. The Robin transmission conditions (RTCs) is used as the coupling in FEM and BEM domains, and the second-order transmission conditions (SOTCs) is used as the coupling in different FEM subdomains. In numerical examples, the accuracy and effectiveness of the method have been verified.
