An extension of the adaptive absorbing boundary condition method

The initial problem we want to solve is the radiation of an antenna located on a large metallic structure. The proposed approach is based on a domain decomposition method (DDM) with a new adaptive absorbing boundary condition (AABC). In this paper, we have proposed a new DDM approach coupling finite element method (FEM) and boundary integral equation (BIE). This approach is well-adapted for both radiation and scattering problems in which FEM is used in a reduced zone.
