Energy currents in the field formed by waves with different frequencies

Abstract

The behavior of instantaneous and averaged vectors of the Poynting vector transverse component for the resulting field formed as a superposition of waves with different frequencies and different polarizations is considered. Results of computer simulation and experimental data are obtained for the superposition of frequently differed vortices with different and the same signs of topological charges. It is shown that the captured particle rotates due to the orbital momentum and substantial increase of particle rotation speed in the case of polychromatic radiation as opposed to monochromatic is observed.
