A low-dispersive high-order unconditionally stable finite-difference-time-domain (FDTD) method based on alternating direct implicit technique (ADI) is presented in this paper for the time-domain solution of Maxwell's equation. The stability and dispersion performance of the scheme is investigated. It is observed that the high order scheme reduces the numerical dispersion and anisotropy and therefore leads to the potential eight-times saving computation memory. It is expected that the scheme can… CONTINUE READING
