Keywords:
Metasurface, microwave lens, P-B phase, phase discontinuityAbstract
In this paper, a transmissive periodic metasurface based on double-layer metal wire structure is designed by combining gradient phase theory with Pancharatnam-Berry (P-B) phase theory to control scattering phase of electromagnetic wave. The proposed artificial electromagnetic medium lens can improve the cross-polarized wave conversion efficiency of the phase discontinuous metasurface and ensure the thickness of the lens is ultrathin relative to the working wavelength.
