In this paper, a broadband and highly efficient reflective polarization converter based on Z-shaped metasurface is demonstrated at sub-terahertz (THz) frequencies. The polarizer can convert a linearly polarized (LP) wave to its cross-polarized wave at three resonant frequencies, which can also convert a LP wave to a circularly polarized(CP) wave at other two frequencies. The polarization conversion efficiency for normal incidence larger than 80% is obtained from 0.116THz to 0.26THz. The surface current distributions are demonstrated to investigate the physical mechanism. Furthermore, the performance under oblique incidence shows the broad bandwidth can be sustained as incident angle increases to . The polarizer could be useful for enhancing the efficiency of polarization conversion in THz regime.
