From: Spatial variation of vector vortex beams with plasmonic metasurfaces
(a) The first category of vector vortex beam with the variation of polarization mode in the order of (TE → TM → TE → TM) with m = {1, 1, 2, 2} and n = 0. (a) Simulated beam intensity distributions without polarization analyzer at different propagation distances. (b) The corresponding intensity distributions analyzed with vertical or horizontal linear polarizer. (c) Simulated polarization distributions at different propagation distances. (d,e) The corresponding measured beam intensity distributions. The detailed transition processes of both beam intensity and polarization distributions are shown in the supplementary video.
