Abstract

A specific nonspecular effect which should attend the partial reflectance of a light beam at a plane interference of two isotropic media is considered. The effect should take place when the incident beam carries the well-defined orbital angular momentum, it consists in such a redistribution of the electromagnetic energy inside the reflected beam that the intensity increases at one side from the plane of incidence and decreases at the other. The effect is described on the basis of the concepts of a local angle of incidence and of local reflectivity. The key points of this approach are as follows: the azimuthal variation of the phase of the incident beam stipulates the variation of the local angle of incidence across the interface, this variation, in turn, stipulates the variation of the local reflectivity and, as a consequence, the modulation of the intensity profile of the reflected beam.
