Query: A postprocessing technique for a discontinuous Galerkin discretization
  of time-dependent Maxwell's equations   We present a novel postprocessing technique for a discontinuous Galerkin (DG)
discretization of time-dependent Maxwell's equations that we couple with an
explicit Runge-Kutta time-marching scheme. The postprocessed electromagnetic
field converges one order faster than the unprocessed solution in the
H(curl)-norm. The proposed approach is local, in the sense that the enhanced
solution is computed independently in each cell of the computational mesh, and
at each time step of interest. As a result, it is inexpensive to compute,
especially if the region of interest is localized, either in time or space. The
key ideas behind this postprocessing technique stem from hybridizable
discontinuous Galerkin (HDG) methods, which are equivalent to the analyzed DG
scheme for specific choices of penalization parameters. We present several
numerical experiments that highlight the superconvergence properties of the
postprocessed electromagnetic field approximation.
