摘要
给出了一种新的计算左手材料的有限差分（FDTD）算法，称为移位算子FDTD（SO-FDTD）算法。利用算子之间的移位递推关系，推导出计算左手材料的递推表达式。对左手材料平板透镜和完美透镜的负折射现象进行了仿真实验，仿真结果与理论分析一致。
A novel finite-differenee time-domain （FDTD） method, called shift operator FDTD （SO-FDTD） method, is developed for left hand materials. The SO-FDTD formulation for left hand materials is derived. This method is applied to simulate the perfect lens and the negative refraction phenomena of the left hand mate rials and the simulation results are in good agreement with the theory analysis.
