Abstract

In this paper, we propose a wideband linear polarizer that utilizes metamaterial and metasurface techniques to achieve highly efficient polarization conversion. The proposed polarizer achieves a polarization conversion ratio exceeding 90% at 11.7-16.0 GHz, as confirmed by both simulated and experimental results. The effects of geometric parameters, incidence angle, and polarization angle on the performance of the polarizer are analyzed, and it is demonstrated that the polarizer maintains an extremely high polarization conversion efficiency even under wide-angle incidence. The polarization conversion mechanism is elucidated through the examination of eigenmode and surface current distribution. This work holds significant promise for the control of electromagnetic waves, making it essential for upcoming engineering applications.
