A novel broadband technique to effectively launch plasmons along a single\ngraphene layer at terahertz (THz) frequencies is proposed. To this end, the\ncoupling of the electromagnetic wave from a readily available plasmonic\nwaveguide established by a periodically corrugated metallic surface to the\ngraphene sheet is proposed. As will be shown, this technique can significantly\nsurmount the need for efficient excitation of plasmons in graphene. For this\npurpose, an analytical technique based on transmission line theory is employed\nto calculate the scattering parameters of the connection of the plasmonic\nwaveguides. In this manner, the gating effects of the graphene waveguide on the\ninput reflection and transmission of the junction are also investigated. For\ncomparison, a full wave numerical simulator is employed.\n
