Acesso em:.https://repositorio.ufpa.br/handle/2011/10956Graphene is a two-dimensional material with good electrical properties that make possible new telecommunications applications in telecommunications on the terahertz range. This work presents an alternative analysis of the scattering problem in a graphene sheet using the impedance transform. The Green functions, electromagnetic fields and properties of the plasmonic surface wave on the graphene are demonstrated. The numerical results show the spatial field distributions and spectral analysis of the plasmonic wave as a function of media properties, frequency and chemical potential. The results show that the impedance transform is adequate for scattering analysis in graphene sheets because it uses the natural autofunctions of the problem.Acesso AbertoEspalhamento eletromagnéticoAnálise espectralGrafenoTerahertzTransformada de impedânciaElectromagnetic scatteringGraphene sheetSpectral analysisImpedance transformDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAELETROMAGNETISMO APLICADOTELECOMUNICAÇÕES
