摘　　要：研究了光轴平行于界面的单轴各向异性手征介质平板对平面电磁波的反射和透射特性,推导出了反射和透射系数(功率)公式;按介电常数的正负分4种情形给出了反射和透射功率曲线;讨论了手征参数对反射和透射特性的影响,特别是给出了伪布儒斯特角与手征参数的变化关系曲线.The reflection and transmission characteristics of electromagnetic waves by the uniaxially anisotropic chiral slab with the optical axis parallel to the interface are investigated. Formulas of the reflection and transmission coefficients （power） are derived. The curves of powers of the reflected and transmitted electromagnetic waves are presented for four cases of dielectric constants according to their signs. The effects of chirality parameter on the reflection and transmission are discussed. Especially, the dependences of pseudo-Brewster angles on the chirality parameter are plotted.
