Summary: This paper proposes and numerically investigates a graphene metasurface based on split-ring resonators (SRRs) structure, which can achieve highly efficient switchability of anomalous refraction and planar focusing effects. Numerical simulation results show that the proposed metasurface can realize polarization conversion with a transmission amplitude of about 0.4 and achieve a full 2 pi phase shift by changing the geometrical parameters of the SRRs structure. Furthermore, the efficiency of cross polarization transmission is highly dependent on the Fermi energy level of graphene. By designing a spatially phase profile and arrangement of unit-cell structure, anomalous refraction and planar focusing effect can be achieved, with the efficiencies switched by changing the Fermi energy level rather than the physical size.

Summary: The self-healing ability of radially Airy beam is closely related to the size of the broken part. When the broken angle is smaller, the self-healing distance is shorter and the effect is better. However, as the broken angle increases, the self-healing effect becomes worse, showing an inverse proportion relationship between the two.

Summary: This paper proposes an all-metal metasurface structure that can achieve high-efficient reflective circular-polarization conversion and multifunctional terahertz wavefront manipulation in an ultra-broadband frequency range. Numerical simulation results demonstrate the high conversion efficiency and phase control capability of the structure at specific frequencies. Based on the Pancharatnam-Berry phase principle, anomalous reflection, reflective planar focusing, and vortex beam generation are realized. This research is significant for enhancing the performance of reflective-type all-metal metasurfaces and has great potential in wavefront manipulation and communication applications in the THz and optical regions.
