Abstract

The application of the magnetic metamaterials with positive (over one) permeability is proposed. The Brewster effect is one of the methods to eliminate unwanted reflection occurred at the material boundary of different indices. The message in this paper is that the magnetic responses of the metamaterial enable us to realize the Brewster effect not only for p-polarized light but also for s-polarized one. This new finding has the significant consequence that if we could induce the Brewster effect for both p- and s-polarized light simultaneously, the light could pass though the material boundary without any reflection loss at all. Based on this idea, we theoretically demonstrate the Brewster windows for both polarizations by introducing a uniaxial magnetic metamaterial whose values of the permittivity and permeability depend on the direction of the material. Numerical simulations prove that this metamaterial-based optical device realizes the reflectionless light transmission through the interface between vacuum and glass.
