An Interior Penalty Discontinuous Galerkin Time Domain Method for Nanophotonic Applications

In this work, an interior penalty discontinuous galerkin time domain method is developed for the discretization of the 3D time-domain Maxwell's equations coupled to a Drude dispersion model for nanophotonic applications. High order hierarchical vector basis and high order explicit Low-Storage Runge-Kutta scheme is applied for the space and time discretization, respectively. Numerical experiment is implemented to demonstrate the accuracy of the proposed method.
