Abstract
A linear polarization converter based on metasurface operating in reflection mode was demonstrated. Simulated results indicate that the polarization conversion ratio (PCR) of the polarization converter is more than 90% in the range of 4.73-10.93 GHz. The experiment results are well consistent with the simulated results. Moreover, the bandwidth of linear polarization converter can be tuned by metal patch length and T-shaped slot width. The converter has angular stability below 36° and polarization insensitivity under the x- and y-polarized incidence waves, which makes it promising for applications in orbital angular momentum beam generators and beam steering systems.
