研究了光轴平行于界面时单轴各向异性手征介质中实现负折射的条件, 并详细分析了该介质中两个本征波在不同电磁参数和手征参数下折射角随入射角的变化规律. 结果表明, 利用单轴各向异性手征介质实现负折射, 条件更加宽松, 甚至在弱的手征参数下也可能实现负折射, 且在不同的介电常数、手征参数和入射角下, 该手征介质中两个本征波的相折射角存在很大的差异, 在特殊条件下, 某一个或两个本征波不能在介质内传播.

The condition to realize the negative refraction in the uniaxially anisotropic chiral medium with an optical axis parallel to the interface has been investigated. The variations of refraction angles of two eigenwaves with the incident angle for different electromagnetic parameters and chirality parameters are also analyzed. The results show that the uniaxially anisotropic chiral medium is easy to realize the negative refraction, even though it has a small chirality parameter. And for the different permittivities, chirality parameters and incident angles, the phase refractive angles of the two eigenwaves in the uniaxially chiral medium are distinctly different. In a peculiar condition, one or two eigenwaves cannot propagate in the medium.-
