Faraday Effect on Negative Refraction in Uniaxial Anisotropic Plasma Metamaterials

Negative refraction is the name for an electromagnetic phenomenon in which light rays are refracted at an interface in the reverse sense to that normally expected. A uniaxial anisotropic plasma metamaterial that exhibits negative refraction is demonstrated and the necessary conditions are derived for negative refraction. The Faraday effect on the negative refraction in the proposed plasma metamaterials is discussed. Parameter dependences such as plasma filling factor, dielectric constant of background materials, and external magnetic field are calculated and discussed.
