Paper Abstract

We propose a generalization of Artmann's method for three-dimensional beams. This generalization, that does not consider a symmetry coordinate for the incident beam, allows its use in non-isotropic interfaces. We apply it particularly to the study of the refraction of a beam that is limited in two directions and that impinges on a uniaxial crystal-isotropic medium interface in presence of inhibited reflection. As known, the direction of the energy flux of a three-dimensional incident beam can be obtained (to first order and considering paraxial approximation) from the interference patterns of two two-dimensional beams. Each beam can be obtained from the superposition of two plane waves. In the first beam, the normals to the wave fronts are contained in the same incidence plane and they impinge with different angles; in the second, they are contained in different planes of incidence but with the same angle. We show that the refracted ray, in presence of inhibited reflection, suffers a lateral displacement that is not contained in the plane of incidence. The refraction of the first two-dimensional wave packet takes into account the longitudinal displacement whereas the refraction of the second allows us to calculate the transversal displacement.
