Abstract :
A new discontinuous Galerkin Spectral Element Time Domain (SETD) method for Maxwell´s Equations is proposed. It can suppress spurious modes using basis functions with the same order of interpolation for electric field intensity and magnetic flux density (i.e. the EB scheme). Compared to SETD based on the EH scheme, which requires different order of interpolation polynomials for electric and magnetic field intensities, the EB scheme SETD reduces the number of unknowns and computation cost. The discontinuous Galerkin method is employed to implement domain decomposition for the EB scheme to allow large-scale computation.
