We propose a theoretical approach to investigate plasmonic properties of mid-infrared graphene-based metamaterials. The artificial structures are composed of periodic arrays of graphene plasmonic resonators on dielectric thin films. Optical resonances are very sensitive to structural parameters and dielectric functions of both substrates and medium. The sensitivity at the mid-infrared regime can be exploited to design biosensors due to the same frequency order as molecular vibrations. Our numerical results are in accordance with previous experiments
