| 摘 要： | 负折射介质有着特殊的电磁特性，将其应用到现代微波系统设计中可以大幅度的提高系统的带宽和增益特性，因此对它的仿真算法研究也备受人们关注。在传统时域有限差分算法模型下结合Drude等离子体计算模型来仿真负折射介质，并将其拓展到三维，研究散射体在涂敷该介质时的近区场特性，修正电流磁流的剖分方法，并比较修正前后的误差。

| Abstract: | Negative refraction medium（NRM）has special electromagnetic characteristics which can obviously expand bandwidth and increase total gain in mocrowave systems. So research on the simulation method is very important. We discuss Drude-FDTD model and apply it to NRM simulation, then extend it to a three-dimensional model and simulate near field of an object with a NRM cloaking. Electric current and magnetic current simulation method is modified, and the errors before and after being modified are compared. |
