Zhou Zhe-Hai†, Zhu Lian-Qing
       
(a) Polarization orientation of ASPBs, and (b) the polarization distributions of radially polarized beams, (c) azimuthally polarized beams, and (d) a kind of high-order ASPB with P = 3, where the arrow refers to the polarization orientation at the local position in the beam cross section.
