Abstract: Uniform phase gradient metasurfaces exhibit spatially varying platforms, resulting in deflecting a beam in a desired direction, while appropriately designed nonuniform phase gradient metasurfaces (NPGMs) may generate controllable multi-channel deflection. Using chiral symmetry of geometric phase and the interference between dual scattering channels, we propose the design of NPGMs made of identical nanorods (NRs) to realize anomalous reflection of arbitrary polarization under the incidence of arbitrary linear or elliptical polarization. In addition, we design NPGMs for the detection of the polarization state of the incidence by measuring the intensities of four reflected channels. The detection range of the state of polarization (SOP) of the incident beam can cover the entire Poincaré sphere. All the results based on Huygens theory agree well with those from finite-difference time-domain (FDTD) simulation. Our design of the metasurfaces based on the geometric phase has the characteristics of easy integration, multi-function and dispersionless, and provides general design guidance for metasurface polarization devices.
