| description | Abstract As a unique two-dimensional atomic material, graphene offers excellent mechanical properties, dynamically tunable surface conductivity, ultra-high carrier mobility, and optical transparency, making it great potential for novel electromagnetic devices. However, dynamic manipulation of microwave polarization has not been experimentally realized in a graphene-assisted metasurface. In this paper, we present a general strategy for designing graphene-based active meta-device for achieving dynamic polarization control at microwave frequencies. When illuminated by a linear-polarized incident wave, the polarization angle of the reflected wave can be dynamically controlled by shifting the bias voltage applied to graphene. The simulated and measured results reveal that the proposed graphene-based meta-device offers a novel approach to the manipulation of microwave polarization and has potential applications in antenna, sensing, and communications. |
