Acesso em:.https://repositorio.ufpa.br/handle/2011/3755This work presents the development of a computational algorithm for electromagnetic scattering analysis of isolated plasmonic nanostructures. The tridimensional Method of Moments (MoM-3D) was used to solve the electric field integral equation, and the Lorentz-Drude model was used to represent the complex permittivity of the metallic nanostructures. Based in this model, a computational algorithm written in C language was developed. As example of application and validation of the code, two classical electromagnetic scattering problems of metallic nanoparticles are analyzed: nanosphere and rectangular nanorod, where the spectral response and near-field distributions were calculated. The obtained results were compared with other models and a good agreement and convergence was observed.porAcesso AbertoNanoplasmônicaAlgoritmos de computadorMoM-3DModelo Lorentz-DrudeNanoestruturas metálicasDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::SISTEMAS DE TELECOMUNICACOES
