Abstract: Many metasurfaces have problems such as low transmittance, because they can only produce electrical responses. To improve the transmittance, based on the new paradigm of Huygens metasurface planar optical devices, a metal-medium-metal type unit cell composed of a group of antisymmetric C-shaped ring resonators (CSRR) is designed, and the unit cells are arranged as Huygens metasurface lens according to certain rules. Compared with the traditional optical lenses, the performance of the transmission components is improved and the thickness of the device is reduced. By adjusting the geometric parameters of the unit structure, the resonator can achieve 360° full phase coverage, and the transmission coefficient can be maintained above 0.6. Based on the design of the phase profile, the deflection lens and convergence lens of electromagnetic waves with certain frequency are realized. The designed Huygens metasurface is insensitive to the polarization direction of the incident wave, and shows broadband deflection and focusing characteristics.
