Abstract
Some computations about the reflectivity of a light wave incident to an anisotropic and inhomogeneous medium are reported here. To explain experimental results concerning a nematic liquid crystal distorted by a Poiseuille flow, we introduce an absorption coefficient (χ = 10−4), simulating the global losses in the propagation of the electromagnetic plane wave. Maximal tilt angle and surface tilt angle are simultaneously revealed by two “critical” angles.Keywords
