NOVELTY - The utility model claims a cylindrical groove waveguide structure based on graphene double-curved metamaterial, the cylindrical groove waveguide structure comprises a sixteen-period coaxial circular ring and a circular groove; the innermost layer of the cylindrical groove waveguide cross section is solid Ge cylinder, a layer of graphene and a layer of Ge ring form a cycle ring; the ring composed of graphene and Ge ring arranged in eight cycles from inside to outside, and then is MgF ring groove; finally, it is a ring composed of eight periodically arranged graphene and Ge ring. The cylindrical groove structure waveguide uses the columnar groove structure waveguide structure to replace the original planar groove structure; when the light is vertical to the structure, the optical field is well limited in the structure of the circular groove area; and it can transmit the radial polarized light; because the structure of the structure is compact, the size is small, the integration degree is high, can be used for the integrated optical path of high density, also can be applied to the field of biochemical sensor and so on, and has wide application prospect.
