The Discontinuous Galerkin Time Domain (DGTD) methods are now popular for the solution of wave propagation problems required for the accurate transient modeling of systems involving electromagnetic waves in many emerging technologies. While Yee's explicit, energy-conserving FDTD method is still prominent but restructed to structured grids and second-order accuracy, DGTD methods 1) are able to deal with unstructured, possibly locally-rene d meshes around complex geometries, 2) remain fully… CONTINUE READING
