| description | A one-dimensionally polarization-independent retrodirective metasurface (PIRMS) is proposed in this letter. The retrodirective metasurface (RMS) consists of ring structures on its ground plane to achieve the polarization-independent characteristics. The reflection phases of unitcells of the metasurface can be controlled by the radius of the ring structure, and the dimension of the supercell with the 2π phase variation depends on an incident angle and operation frequency from the generalized Snell’s law. To verify its feasibility, two kinds of RMSs to operate at two retrodirected angles of 20° and 40° are designed and measured at 5.8 GHz. The measured retroreflected power efficiencies are more than 94% and 92% at the retrodirected angles of 20° and 40°, respectively, regardless of the polarization. The results show that the proposed RMS has good performances independent of polarization. |
