Recent Progress in the Simulation of Plasmonic Systems with the DGTD Method — •Jens Niegemann — Institut für Feldtheorie und Höchstfrequenztechnik (IFH), ETH Zürich, Switzerland

Due to its flexibility and efficiency, the discontinuous Galerkin time-domain (DGTD) method has established itself as a popular method in the field of wave propagation. Here, we discuss our recent advances in using the DGTD method for the simulation of plasmonic and nanophotonic devices. In particular, we demonstrate how a memory-efficient formulation of curvilinear elements together with an implementation on graphics processing units (GPUs) significantly reduces the computational time. This allows large parameter scans or numerical optimizations with relatively little computational power.
