Keywords:graphene, split ring resonator, metamaterial

Split ring resonators are used as a fundamental constituent of metamaterial to obtain negative permeability. In the last meeting, we showed transmission, reflection, and absorption spectra in the terahertz region of plasmonic split ring resonators consisting of graphene. Here, we will demonstrate modulations of resonance frequency and optical oscillator strength of graphene split ring resonators by gating.
