Behavior of the transversal component of the Poynting vector in the area of interference trap

The mechanisms of formation and operation of so-called "interference trap" are presented. The formation of the interference trap by beams with different curvature, ratio of the intensities and phase difference are shown. The results of the computer simulation of the Poynting vector behavior in the area of the interference trap are analyzed. The transformation of angular momentum of vortex beam under interference with smooth ones is shown. Distribution of the transversal component of the Poynting vector for the interference trap, formed by the vortex with different topological charge is analyzed.
