Abstract : We present the Discontinuous Galerkim methods for solving Time-Domain DGTD Maxwell-s equations coupled to the Drude model arising from nanophotonics. Model Order Reduction MOR techniques are employed to reduce the simulation time. We have considered a Proper Orthogonal Decomposition POD method, Krylov-subspace based operator exponential approach and Padé approximation approach. Numerical results show that the proposed DGTD + MOR methodology is much faster than the full DGTD methods.

Keywords : Maxwell-s equations nanophotonics time-domain discontinuous Galerkin method model oder reduction
