| 摘 要： | 电磁波在负折射率介质中传播时,材料的介电常数和磁导率均为负数,从而表现出一些奇特的特性。为详细了解电磁波在正负折射率介质分界面的反常折射现象,文章讨论了正负折射率介质分界面的反射和折射规律,并用有限元软件Comsol Multiphysics对反射和折射现象进行仿真,同时对与理论分析一致的仿真结果以图像形式进行了显示。

| Abstract: | When electromagnetic wave spreads in a negative refractive index medium, because of the negative permittivity and negative permeability, it shows some peculiar properties. In order to understand the unusual refractive phenomenon of electro-magnetic wave at the interface between positive and negative refraction index medium, the paper discusses the reflective and refractive laws at the interface between positive and negative refraction index medium, and simulates the reflective and refrac-tive phenomenon by using the finite element software Comsol Multiphysics. At the same time the simulation result that agrees with the theoretical analysis is shown in the form of images. |
