Análise Espectral de uma Folha de Grafeno Excitada por uma Linha de Corrente Magnética

Graphene is a material that possesses properties with potential applications in telecommunication in the terahertz band. In this work, it is presented a spectral analysis of the electromagnetic scattering of a graphene sheet fed by a linear magnetic current. The method uses the representation of the two-dimensional Green's functions in terms of Fourier transform and one-dimensional Green's function. It is presented numerical results of spatial distribution of magnetic field and spectral analysis of the plasmonic surface wave on the graphene. The results show the influence of the chemical potential and permittivities of the different medium on the characteristics of the plasmonic mode.
