Plasmonic vortices for tunable manipulation of target particles, using arrays of elliptical holes in a gold layer
Here, we numerically prove that light with linear polarization can be coupled to surface plasmon polaritons at an elliptical hole perforated in a gold layer to generate plasmonic vortex (PV). Benefiting from the smooth variation of the minor to major ellipse axes, a gradual variation in the phase pr...
