Abstract
Aiming at the efficient radiation simulation of anten-nas with dielectric slabs and spatial multiscale features, a discon-tinuous Galerkin (DG) scheme for the multi-region surface inte-gral equation is presented in this letter. Boundary lines between different materials can be handled independently without merging and reducing unknowns at the junction, which simplifies the cal-culation. Numerical experiments of different kinds of antennas are carried out to verify the accuracy and efficiency of the proposed method through comparisons.
