Abstract

he results of the study of the wave beam refraction by the flat border of isotropic dielectric and monaxonic crystal are brought. The refraction of wave beam on the border of monaxonic crystal has a row of the specific features, related to that direction of distribution of phase
In a usual wave beam the wave normal of axial wave coincides with the ray vector of this wave. In an unusual
beam they do not coincide in this connection, axes are perpendicular to the wave normal and not perpendicular ray.
Passing is therefore done to the oblique-angled wave - ray system that descript position of power center of unusual
bunch is correct.
A case is widely used in appendixes, when an optical axis lies in plane falling, here a ray lies in the same plane and a corner between a wave normal and ray is determined by a simple formula.
The change of basic parameter of beam, called the variance, is determined by the change of phase, therefore for an unusual beam it depends on a wave coordinate, but not on the ray. The operator of transformation of variance is certain on the border of division, that allows to obtain information about the structure of refracted wave
beams without the decision of border task.
Knowledge of operators of transformation for the variances of refracted wave beams easily allows to define the structure of the field of the last wave beams at falling of wave beam on the arbitrary stratified structure with flat borders, containing the layers of isotropic dielectric and monaxonic crystal
Key words: wave beam, monaxonic crystal, tensor of dielectric penetration.
