摘要：

We propose polarization control system based on graphene-dielectric multilayer stacking arrays and numerically investigate the characteristics of transmission spectrum and phase shift. The results show a high extinction ratio polarizer, and the operating frequency of which can be designed via changing the geometric parameters and Fermi level. In addition, a large phase difference is generated in the x and y directions, and polarization control can be achieved by the superposition of the two modes along the orthogonal directions. The proposed structure demonstrates excellent polarization manipulation capability, ultrathin thickness and flexible control of the operating frequency, providing a good avenue for integration of device in the infrared.
