N2 - A discontinuous Galerkin method (DG) is presented to accurately calculate electromagnetic scattering from objects with impedance boundary condition (IBC) surfaces by using well-conditioned self-dual integral equations (SDIE). More importantly, a better understanding of DG methods is obtained. The superfluous items are omitted from traditional DG methods and an efficient and refined formulation called R-DG-SDIE is proposed. Numerical results demonstrate this proposed R-DG-SDIE formulation has faster convergence and less computation than those directly extended from previous interior penalty (IP) DG formulations.
