We present a novel method for the analysis of intricate optical waveguides. The method relies on a discretization of the Maxwell’s vector wave equation with an Interior Penalty Discontinous Galerkin Method (IPDG) combined with a standard FEM. This method is spurious-free for a large parameter that penalizes the tangential flux. We present results for optical waveguides, including a leaky plasmonic one.
