Polarization multiplexed multifunctional metasurface for generating longitudinally evolving vector vortex beams

•We propose a novel methodology to design polarized multiplexing multifunctional metasurfaces.•This approach integrates multiple vortex modes into a single-layer metasurface.•The generated vortex beams have the characteristics of longitudinal evolution in three polarization channels.•This approach provides a new option for the research of integrated optics.
