“…The phenomenon of negative refraction which is shown in the negative uniaxial anisotropic materials has imaging applications in superlenses beyond the diffraction limit [11]. A detailed analysis of the reflection, refraction characteristics, and the features of the Brewster angle for both TM and TE waves have been investigated at the planar interface associated with the uniaxial media [3,10,[12][13][14][15]. As one knows, the Poynting and wave vectors in anisotropic materials are not necessarily collinear.…”

In this paper the reflection and refraction of the electromagnetic waves from the planar interface of an anisotropic medium are investigated. The considered anisotropic medium is a uniaxial material whose optical axis lies in the incident plane and makes an arbitrary angle with the normal to the interface. It is shown that the directions of the wave and Poynting vectors of the transmitted wave depend on the incident angle and the orientation of the optical axis of the uniaxial material. Also, the situation that the negative refraction can happen for such media is obtained. In addition, the dependence of the Brewster angle to the orientation of the optical axis of the uniaxial material is considered. More interestingly, it is shown that there is a situation for which the wave and Poynting vectors of the transmitted transverse magnetic wave are parallel.
