Birefringence: property of an anisotropic medium in which light propagates differently depending on its polarization
Extraordinary refraction index: in a birefringent uniaxial material, said of the refractive index seen by that of the two refracted rays from a single incident ray whose polarization is not perpendicular to the optical axis
