Electromagnetic Scattering Computation by Means of the Hybrid FEM-SRBCI Method

In this paper, the authors propose a modified version of the hybrid finite element method-Robin boundary condition iteration (FEM-RBCI) method to solve scalar scattering problems, such as 2-D electromagnetic and 3-D acoustic ones. In the modified method, called FEM-singular RBCI, the integration surface coincides with the truncation one, so that the integral equation becomes singular.
