| description | We present a straightforward metamaterial structure based on a graphene monolayer, which comprises a single graphene block and two graphene strips. This innovative design enables plasma-induced transparency (PIT) phenomenal generation by harnessing the interplay between bright and dark modes. To elucidate this phenomenon, we conduct comprehensive theoretical calculations that corroborate the findings of simulate results from finite difference time domain (FDTD). Furthermore, we explore the PIT phenomenon across various Fermi energy levels while also investigating the associated slow light effect in relation to the structural parameter, Fermi energy level, and carrier mobility. By increasing the carrier mobility from 0.4 to 3.4 m2/(V⋅s), the group index can be elevated from 80 to 430. Consequently, this graphene-based metamaterial holds promise for inspiring novel approaches to the design of modulators, optical switches, and devices for manipulating slow light. |
