Abstract

Addressing the problem of Pancharatnam-Berry (PB) phase metasurface mutual coupling and single functionality under orthogonal circularly polarized wave incidence, a circularly polarized multiplexing focusing metasurface lens with polarization conversion functionality operating at 24 GHz is proposed using the method of jointly modulating PB phase and resonance phase. The metasurface unit is composed of two layers of dielectric plates covered with metal patterns on both sides separated by air. By varying the parameter sizes of each joint of the windmill-shaped metal pattern, the resonance phase of the unit can be independently controlled in the x-polarization and y-polarization directions, achieving a phase coverage close to 320° while maintaining a transmission magnitude greater than 0.8. By rotating the metal pattern, the size of the PB phase can be freely controlled. Adjusting the parameters of the metal pattern, the unit has a phase difference of 180° in the x- and y-polarization directions, achieving polarization conversion of circularly polarized waves, with its polarization conversion rate (PCR) approaching 100% near the operating frequency band. Simulation and test results show that under left-handed and right-handed circularly polarized wave incidence, the metasurface lens achieves single-point focusing effects at different positions, with focusing efficiencies of 45.6% and 45.9%, and focal spot sizes of -3 dB of 8.8 mm and 8.4 mm, respectively. This work is expected to be applied in fields such as K-band satellite communication, wireless power transmission, and 24 GHz automotive millimeter-wave radar.
