NOVELTY - The utility model claims a-half of the ring based on the graphene sensor coupling structure, belonging to the graphene material is applied on the sensor field. the sensor is a three-dimensional periodic structure, the structure is composed of graphene pattern array to deposit silicon dioxide on the substrate, the sub-structure uses a graphene ring semi-ring with the graphene coupled to generate electromagnetic induced transparency phenomenon. The utility model is mainly through the finite element method simulation calculates the graphene structure at different chemical potential, different ring offset distance, of the transmitted spectrum under different medium refractive index, and further optimizing the structure under the simulated direct a computing result, to make it have the ability can excite the electromagnetic induced transparency phenomenon at infrared band in different locations, with good sensitivity and tunability. The utility model has simple structure, and it is convenient to be processed and manufactured.
