Abstract
In this work, we present a method for generating vector vortex beams with metasurfaces. A Jones calculation is employed to theoretically analyze the phase and polarization transformation from metasurfaces. The experimental results are shown to agree well with our theoretical calculation. Lastly, as a geometrical representation, the hybrid-order Poincaré sphere is proposed to describe the evolution of polarization state and phase of light wave propagating in metasurfaces. The hybrid-order Poincaré sphere can intuitively demonstrate the change of polarization state and. So it can also become an effective tool to provide help in designing metasurfaces.
