Veselago demonstrated that metamaterials with both negative permittivity and permeability may display this property in the reverse sense. This phenomenon may happen different for oppositely-handed circular polarizations in the Faraday effect and is said to happen "double" in materials like calcite, which are (*) birefringent. This phenomenon is modeled by setting the ratio of the sines of the angles in question equal to the reciprocal ratio of the indices of the media. For 10 points, name this phenomenon, wherein a chan

This phenomenon is modeled by setting the ratio of the sines of the angles in question equal to the reciprocal ratio of the indices of the media. For 10 points, name this phenomenon, wherein a change in wave speed results in a change in wave direction.
