摘　　要：We theoretically and numerically investigate the diffraction properties of surface plasmon polariton（SPP） in binary graphene sheet arrays. The single SPP band splits into two minibands by alternatively arranging the graphene waveguides with two different chemical potentials. Numerical simulations show that SPP beams in the array split into two different paths due to the different diffraction relation.We theoretically and numerically investigate the diffraction properties of surface plasmon polariton（SPP） in binary graphene sheet arrays.
