Shift of application point of angular momentum in the area of elementary polarization singularity

It is shown that C-points are associated with the singularities of the azimuth of the averaged transversal component of the Poynting vector. It is shown that such field structures may be obtained by superposition of orthogonally circularly polarized beams. It is established that a Poynting singularity shifts the C-point position relatively under definite changes of amplitude or phase of the superposing beams. Thus, the point of application of the averaged angular momentum also shifts. The results of a computer simulation and experimental results are presented. The perspectives of a new type of optical trap creation are discussed.
