Manipulation of Energy Flow with X-Type Vortex
In this study, a new method for manipulating energy flow in a 3D vector field is proposed.In this method, an azimuthally-polarized beam hybrid willows for sale with a noncanonical vortex, the X-type vortex, is focused in a high-numerical aperture system.It is found that, instead of the invariance of the energy flow which is characteristic of the tr
