Paper Abstract

We investigate the synthesis of two-dimensional surface plasmon vortex power flows by a plasmonic vortex lens excited by oblique incident beams. It is shown that the plasmonic vortex lens can generate the off-centered vortex flows, the centers of which are determined by the incidence angle of the excitation beam. The theoretical analysis of the relationship between the off-center shift and the incidence angle is described. Furthermore it is shown that the illumination of two unparallel coherent incidence beams produces dual-vortex flows by the coherent superposition.
