The phase profiles of the reflected circularly polarized waves can be freely manipulated by virtue of a co-polarization reflective metasurface. Based on the co-polarization reflective metasurface, a circularly polarized wave reflection focusing metasurface can be achieved, it can make the reflected waves focus at a focal spot under the normal incidence of circularly polarized plane waves. In this paper, a reflection focusing metasurface is designed. It is found that around the central frequency f=16 GHz, the reflected waves focus on a focal spot above the metasurface with a focal distance L=200 mm under the normal incidence of right-handed circularly polarized waves. However, in the case of normal incidence of left-handed circularly waves, the reflected waves focus on an imaginary focal spot below the metasurface with the focal distance L=-200 mm. The beam-width at the focal spot and focal depth are also calculated by using CST Microwave Studio. The simulation results indicate that the beam-width at the focal spot is approximately equal to the operating wavelength. Therefore, the circularly polarized wave reflection focusing metasurface has a good performance for focusing the reflected waves. In addition, the proposed focusing metasurface displays the advantages of the long focal depth and the broad operating bandwidth.
