Item Acesso aberto (Open Access) Controle do diagrama de radiação de dipolo de grafeno pelo potencial químico(Universidade Federal do Pará, 2018-12-13) PINTO, Gabriel Silva; COSTA, Karlo Queiroz da; http://lattes.cnpq.br/7932708321834647This 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.
