摘　　要：研究了电磁波在各向同性常规媒质和主轴与界面不重和的各向异性异向介质表面的反射和透射特性,给出了反射系数和透射系数的表达式。根据各向异性异向介质色散关系的不同,分四类讨论了主轴旋转对全反射和全透射现象的影响,并得到了不同情况下发生全反射和全透射的旋转角范围表达式。结果表明:在这种媒质界面上的波传输特性与常规界面有很大不同。The characteristics of reflection and refraction of electromagnetic waves at the interface between an isotropic regular media and an anisotropic metamaterial cut along nonprincipal axes are investigated, and the expressions of the reflection and transmission Coefficients are presented. In terms of the dispersion relation of the anisotropic metamaterial, the influence of the rotation of the principal axes on the total reflection and total transmission phenomenon is discussed in four classes, and besides, the ranges of the rotation angle for the total reflection and total transmission occurrence are given for each case. It is found that the propagation of waves at such interfaces is significantly different from that at regular interfaces
