NOVELTY - The utility model claims a multifunctional slow light device based on broadband electromagnetic induction transparent, belonging to the technical field of radio communication, comprising a medium substrate; the top surface of the medium substrate is fixedly provided with a graphene quasi-dark mode resonant unit; the graphene quasi-dark mode resonant unit comprises four quasi-dark mode resonant sub-units; the quasi-dark mode resonant sub-unit is a smiling face type structure; the smiling face type structure of each quasi-dark mode resonance sub-unit rotates 90 degrees around the origin centre and is the same as the smiling face type structure of the adjacent quasi-dark-mode resonance sub-unit; the bottom surface of the medium substrate is fixedly provided with a graphene bright mode resonant unit; the graphene bright mode resonant unit comprises a first bright-mode resonant sub-unit with positive eight-side annular shape and a second bright-mode resonant sub-unit with eight-petal pattern; the first bright-mode resonant sub-unit and the second bright-mode resonant sub-unit are set with the origin centre as the centre point. The utility model can have the slow light effect with wide frequency band range in the terahertz wave band.
