Abstract
Metamaterials are synthetic special structural units, usually in the wavelength or subwavelength range. When the incident light is coupled with the structural element, the free electrons on the surface can generate surface plasmons under the periodic drive of electromagnetic wave. In this paper, we mainly study the transparency of dynamically adjustable plasma-induced periodic graphical graphene nanoribbons. This paper discusses the geometric parameters that affect the variation of PIT. The gap distance G and the disc moving distance S can change the coupling strength of the light and dark modes, and the variation of coupling strength can adjust the transparency and frequency band width of PIT window. The Fermi energy of graphene can be changed by adjusting the electrical conductivity of graphene, and the change of Fermi energy can also regulate the PIT effect.
