摘要

描述了一种六阶各向同性时域有限差分算法。该算法在辐射、空腔等需要高全局各向同性的问题中具有重要意义。该算法对单频问题也很有吸引力，因为单频问题可以通过引入人工材料色散校正来消除色散。

A higher order isotropic FDTD scheme using artificial dispersion via controllable higher order time derivatives

A sixth order isotropic FDTD algorithm has been described. The algorithm can be of great importance in cases where high global isotropy is required such as radiation and cavity related problems. The algorithm is also very attractive for single frequency problems where dispersion can be easily eliminated by introducing correcting artificial material dispersion.
