摘要：

We designed a linear polarization converter based on metasurface and simulated its functionality. It has a broad bandwidth and operates in the terahertz frequency range (0.4-1.2 THz). The polarization converter consists of a polyimide substrate, a metal grating and a bimetallic split ring resonator. In a bimetallic split ring resonator, the gaps between the rings are rotated by 90 from one another. The structure is simulated by commercial software CST STUDIO SUITE. The results show that the device successfully converts the polarization of terahertz wave from y to x. This structure also has high stability in terms of incidence angle and operates efficiently in the range of 0 to 45.This kind of polarization converter has a wide application prospect in satellite communication, radar detection, 3D imaging of displays, and other fields.
