Abstract :
A High-order FDTD method has been presented in this paper. The numerical characteristics of the scheme including stability, dispersion and convergence have been investigated. It is observed that the higher order scheme has, the lower numerical dispersion error has, namely, the larger spatial stencil size decrease the numerical dispersion error. Several different cases researches and comparison with the conventional FDTD and the multiresolution time domain (MRTD) methods demonstrate that the High-order FDTD method as a time domain high order method is useful and valuable to study.
