Abstract: (1895 Views)
In this paper, by inserting an array of silver L-shaped nanorods between two layers of graphene, we propose a chiral metasurface in which circular dichriosm is tunable. Left and right-handed circularly polarized lights are normally and obliquely incident onto the proposed structure and circular dichroism spectrum is calculated for different Fermi energies of graphene. Our simulated results demonstrate that maximum value of circular dichroism spectrum and the wavelength in which maximum occurs can be tuned by changing the Fermi energy.
