Paper Abstract

The features of e m inhomogeneous polarized field, which concern an angular momentum, are considered. It is shown that the e-m field produced by differently polarized optical beams may carry orbital angular momentum. Such angular momentum arises in field area with the point of circular polarization (C -point). Superposition of relatively simple orthogonally polarized beams is considered. Experimental results of particles capturing by such focused beam are presented. On the other hand, in the vicinity of s -contour (field line with linear polarization) spin angular momentum vanishes. At the same time such angular momentum appears when superposition of beams with different wave-length is considered.
