Modeling Metallic Nanostructures using a Discontinuous Galerkin Approach — •Jens Niegemann, Michael König, Christopher Prohm, Timo Köllner, and Kurt Busch — Institut für Theoretische Festkörperphysik and DFG-Center for Functional Nanostructures (CFN), Karlsruhe Institute of Technology (KIT), 76128 Karlsruhe, Germany

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. Furthermore, the method is readily extended to also treat hydrodynamic equations, which allows us to also model the nonlocal and nonlinear properties of metallic nanostructures.

Here, we discuss our recent advances in using the DGTD method for the simulation of plasmonic devices. In particular, we present first results on a full hydrodynamical simulation of small metallic nanostructures.
