Modeling Metallic Nanostructures using a Discontinuous Galerkin Approach — •Jens Niegemann1,2, Michael König1,2, Richard Diehl1, Christopher Prohm1, and Kurt Busch1,2 — 1Institut für Theoretische Festkörperphysik, Karlsruher Institut für Technologie — 2DFG Forschungszentrum Center for Functional Nanostructures (CFN), Karlsruher Institut für Technologie
Over the past few years, the discontinuous Galerkin time-domain (DGTD) method has established itself as an extremely powerful and efficient numerical technique in the field of photonic. Due to its combination of an accurate spatial discretization with an explicit time-stepping scheme, the DGTD method is particularly well suited for studying ultra-short and/or plasmonic phenomena.
Here, we present our recent advances in using the DGTD method for the simulation of metallic nanostructures. In particular, we present the advantages of using higher-order curved elements. Furthermore, we will discuss some of our recent developments with respect to the improvement of the time integration.
