摘要：

In this paper, we propose a wideband and high-efficiency reflective polarization conversion metasurface (PCM) based on anisotropic metamaterials. The PCM has a period of sub-wavelength and simple design with a double-meander-line-shaped resonator printed on a metallic copper plate backed dielectric substrate. Owing to strong anisotropic properties and multiple plasmon resonances at neighboring frequencies, the PCM has a simulated fractional bandwidth of 82.3% from 8.40 GHz to 20.15 GHz with a polarization conversion ratio over 0.9. Numerical analysis and experimental validation are carried out to study the polarization conversion characteristics of the PCM. In addition, the mechanisms are analyzed in detail on the basis of multiple plasmon resonances and surface magnetic field distributions, respectively. The measured and simulated results obtained are in good agreement, which validates the effectiveness of the simulations and analysis.
