a Abnormal reflection of a VB111. b LG VBs with different TCs (first column) and corresponding interference patterns with a co-axis coherent planar wave (second column) and an inclined coherent planar wave (third column). Far-field diffraction patterns of VBs through a triangular aperture40 (c) and a single slit116 (d). e Near-field diffraction pattern of a VB123. f Polarization distribution of vector VBs on the HPS127. a Reprinted with permission from ref. 111.
