Energy Backflow in Tightly Focused Fractional Order Vector Vortex Beams with Binary Topological Charges
Using the Richards–Wolf diffraction integral, the longitudinal energy evolution on the focal plane of the fractional order vector vortex (FOVV) beams was studied. These beams possessed a vortex topological charge <i>n</i> and a polarization topological charge <i>m</i>, and we...
