Anomalous linear phenomena of anisotropic metamaterial

An anisotropic metamaterial with linear dispersion relation was investigated according to Maxwell equations. Based on the linear dispersion, the relation between the elements of dielectric tensor and permeability tensor was obtained. According to the law of conservation of energy and boundary conditions of electromagnetic field, the propagation direction of wave vector and energy flow between the incident and refractive wave was researched. Light collimation, takes place when TE or TM wave propagates in this anisotropic metamaterial, and the propagation ways of TE and TM are opposite to each other.
