Acesso em:.https://repositorio.ufpa.br/handle/2011/10714This work presents a method of controlling the radiation diagram of a graphene dipole by the chemical potential. The dipole analyzed has rectangular geometry with power supply by voltage source in the center, where each arm of the dipole is maintained to a different chemical potential. The geometry is analyzed by the two-dimensional moments method (MoM-2D) in MATLABr software, with an equivalent surface impedance. Calculations of the main radiative properties of the antenna are presented as a function of the chemical potential. The results show that the greater the difference between the chemical potentials, the greater the displacement of the main lobe of the radiation diagram.Acesso AbertoAntenas de grafenoRadiação em terahertzControle do diagrama de radiaçãoMétodo dos momentos (MOM)Graphene antennaTerahertz radiationControl of radiation patternMethod of momentsDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOESELETROMAGNETISMO APLICADOTELECOMUNICAÇÕES
