Properties of surface plasmon polaritons of the TM type at the interface of an isotropic insulator and a periodic graphene–insulator structure have been investigated. It is established that the presence of graphene in this structure allows one to obtain (in certain frequency ranges) negative effective permittivity and implement the condition for the existence of a surface wave that is practically unabsorbed. The influence of the graphene content in the structure on the characteristics of plasmon polaritons (in particular, the possibility of their significant slowing-down) is demonstrated.
