We find the limiting angle of incidence in the slab for these phenomena to occur and its dependence with the orientation of the crystal axes. We analyze, both in reflection and refraction, the displacement of the ray with respect to the incident one at the output of the slab, finding a potential measure to experimentally study this effect.10 p.application/pdfengBiaxial absorbing mediaNegative reflectionNegative refractioninfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess
