Abstract
We present the comparative analysis of tunable graphene-based metasurface polarizer structure THz frequency range. These polarizer structures have been numerically investigated over the 10 THz to 25 THz frequency range. Reflectance co-efficient, phase variation, and phase difference parameters have been investigated to identify the behavior of polarization effect over the range of 10 THz to 25 THz of the frequency. The proposed polarizer has also been investigated for the different shapes of the top gold resonator structure. The proposed structure is tunable for the range of 0.1 eV–0.9 eV of the graphene Fermi energy. The proposed structure also works on the wide range of the input incident wave of the X and Y polarization. This structure has a small, compact, tunable design and can be used as a fundamental building block in the large THz circuits and structures.
