   Abstract:
   Based on the Fourier representation of spatial derivatives, the recursive convolution approaches, and the perfectly matched layer (PML), we develop a pseudospectral time-domain (PSTD) algorithm for electromagnetic problems involving general dispersive media. As a result of the accurate representation of spatial derivatives, the PSTD algorithm for dispersive media requires only a small number of cells per minimum wavelength, significantly reducing the number of unknowns. Multidimensional numerical results confirm the efficacy of the PSTD algorithm for large-scale inhomogeneous media.
