The staggered-grid Fourier pseudospectral time domain (PSTD) methods have proved to be efficient and accurate in seismic modeling, but less efforts have been extended to electromagnetic wave. In this paper, we apply the staggered-grid Fourier PSTD method in the simulation of three-dimensional electromagnetic wavefields in dispersive soils. The soil is considered as an M-th order Debye medium with...
We report on recent developments aiming at improving the accuracy and the performances of a discontinuous Galerkin time domain method (DGTD) for the simulation of time-domain electromagnetic wave propagation problems involving general domains and heterogeneous media. The common objective of the associated studies is to bring the method to a level of computational efficiency and flexibility that allows...
