Acesso em:.https://repositorio.ufpa.br/handle/2011/12285This work shows a comparative theoretical analysis of plasmonic nanoantennas Yagi-Uda and dipole wireless optical nanolinks. All results found from the isolated antennas at transmission mode such as, input impedance, directivity, gain, radiation efficiency, reflection coeficiente and radiation diagram were obtained by the linear Method of Moments, assitionally, the effect of a silicon dioxide substract on antenna resonant properties were obtained by the Finite Element Method through COMSOL Multiphysics software. The numerical analysis of the nanolink is performed by the linear Method of Moments, witch the transmission power and the near electric field are investigated and optimized for the nanolinks Yagi-Uda/Yagi-Uda, Yagi-Uda/dipole and dipole/dipole. The results show that the Yagi-Uda/Yagi-Uda nanolinks offers an improvement in power transmission at some frequency points over the nanolinks dipole/dipole and Yagi-Uda/dipole. In addition, the results demonstrate that all three links can operate at good transmit power at different frequency points, varying the load impedance of the receiving antenna.Acesso AbertoNanoplasmônicaNanoantenaNanoenlaces ópticos sem fioPotência de transmissãoNanoplasmonicNanoantennaWireless optical nanolinkTransmission powerDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICAELETROMAGNETISMO APLICADOTELECOMUNICAÇÕES
