文摘

A metamaterial (consists of a graphene ring and strip) for terahertz PIT is presented. The weak hybridization between two bright modes leads to a novel PIT window. The window can be controlled by varying geometric parameters and graphene Fermi level. These results may offer great promise for switching, slow light device, and sensing.
