The numerical study of electromagnetic wave propagation in interaction with nanometer scale structures generally relies on the solution of the system of time-domain Maxwell equations, taking into account an appropriate physical dispersion model, such as the Drude or Drude-Lorentz models, for characterizing the material properties of the involved nanostructures at optical frequencies. During the last ten years, numerical methods formulated on unstructured meshes have drawn a lot of attention in computational electromagnetics with the aim of dealing with irregularly shaped structures and heterogeneous media. In particular, the discontinuous Galerkin time-domain (DGTD) method has progressively emerged as a viable alternative to well established finite-difference time-domain (FDTD) and finite-element time-domain (FETD) methods for the numerical simulation of electromagnetic wave propagation problems in the time-domain. In this talk, we will review the development of such a DGTD method for nanophotonic applications.
