Compared with the metal antenna metasurface,the dielectric metasurface has better optical characteristics and smaller ohmic loss in the optical band,which makes it superior.An elliptical cylindrical nanostructured antenna is designed using GaP with excellent transmission characteristics in the visible band.This structure has a transmission efficiency of up to 0.96 in the visible light band.Based on the Pancharatnam-Berry (PB) phase control principle,the metasurface structure composed of the antennas is studied,and its abnormal refraction metasurface and focusing meta-lens are analyzed.It is a highly efficient sub-wavelength structure,and promises great potential for the applications of circular polarization optics,nanolithography,dense storage and biophotonics.
