Omnidirectional total transmission at the interface associated with an anisotropic dielectric-magnetic metamaterial

Based on the Ewald-Oseen extinction theorem, the omnidirectional total transmission of waves incident from vacuum into an anisotropic dielectric-magnetic metamaterials is investigated. It is shown that the omnidirectional total transmission need not limit at the interface associated with the conventional nonmagnetic anisotropic medium. The recent advent of a new class of anisotropic dielectric-magnetic matermaterial make the omnidirectional total transmission become available. It is found that the inherent physics underlying the omnidirectional total transmission are collective contributions of the electric and magnetic responses.
