Abstract
When there is total reflection on an isotropic or an anisotropic interface, the reflected ray suffers a displacement on the interface. This effect, which is known as the Goos-Hänchen effect, has been studied by a great number of authors. If an isotropic-uniaxial interface is considered, the condition of total reflection for one of the refracted rays can be fulfilled whereas the other subsists as a propagating wave. In this paper, we analyse and determine analytically the complex displacement that the ray associated with this propagating wave suffers. Representing the ray by a beam with a Gaussian distribution of amplitudes, we show how this displacement is modified by different configurations of the interface and of the incident waves.
