摘要
从理论上研究了手征负折射材料表面的反射与透射特性,给出了归一化的反射透射功率与入射角之间的关系曲线。当入射波分别为垂直和平行极化波(TE和TM波)时,得到了发生负折射时的布儒斯特角和全内反射角随手征参数和材料折射率的变化关系。手征负折射介质中的一个本征波发生了负折射,其功率流方向与波矢方向相反。
The reflection and refraction characteristics on the surface of a chiral negative refraction medium are analyzed theoretically in this paper,in adolition normalized reflected and refracted power curves as a function of the incident angle are figured out.When negative refraction occurs,the relation of Brewster and total internal reflection angle with the refractive index and chiral parameter is also obtained.As one refracted eigen-wave lies in another side of the normal,the direction of its power flow is opposite to the wave propagation.
