Analytical relations for achieving zero reflection in anisotropic materials

Complete transparency and zero reflection condition in anisotropic materials are investigated, and are undertaken in an analytical study. First, the relations related to multilayer anisotropic media in linear structures are stated, and then, through these relations, zero reflection from layered structures composed of conventional materials and/or metamaterials are studied. The authors have formulated a rule for zero reflection from anisotropic media, and have presented various aspects of such structures from the viewpoints of frequency and the angle of incidence, and have created complete transparency in them.
