Acesso em:.https://repositorio.ufpa.br/jspui/handle/2011/16747In this study, a compact nanoscale plasmonic filter was proposed and numerically analyzed. The plasmonic filter is based on graphene nanoribbons coupled to a disc-shaped graphene resonator with horizontal side cuts and 45o orientation, deposited on a dielectric substrate of silica (SiO2) and silicon (Si) , operating in the THz region. We investigated simple structures that allow tuning the resonance frequency of the resonator. This work provides a viable solution for graphene plasmonic nanofilter structures for future use in highly integrateds plasmonic device applications in THz and FIR regions.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/GrafenoRessonadorGuias de ondasGrapheneResonatorWaveguidesDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOESELETROMAGNETISMO APLICADOTELECOMUNICAÇÕES
