A novel hybridization of higher order finite element and boundary integral methods for electromagnetic scattering and radiation problems.

A novel hybridization of the finite element (FE) and boundary integral methods is presented for an efficient and accurate numerical analysis of electromagnetic scattering and radiation problems. The proposed method derives an adaptive numerical absorbing boundary condition (ABC) for the finite eleme...
