A metasurface with a trapezoidal unit structure is proposed to realize the free regulation of visible light beams. To achieve the adjustment from 0 to 2π transmission phase at the target wavelength, the upper and lower bases and width of the silicon nanocells are changed, and the transmission phase is modulated. The metasurface designed with this structure can control linearly and circularly polarized lights simultaneously and realize focusing under the incidence of both linearly and circularly polarized lights with a wavelength of 640 nm. Additionally, under the incidence of linear polarized light, the focusing characteristics and the influence of the lattice period on these characteristics are studied.This research proposes new ideas for the integrated optics based on the design of metasurface structures.
