In the article the spectra of plasmon-polariton in a three-dimensional periodic structure of graphene ribbons embedded in a medium were studied at the first time and for a fixed carrier concentration, influences on the spectra from ribbon width, interface distance and period of ribbon were shown. Compared to those in monolayer periodic structure of graphene ribbons, sharp differences occur. Furthermore, there always exist a match point where frequencies of the plasmon-polarition and the electromagnetic radiation are the same. The study improved our basic knowledge on plasmon dynamics in graphene and was important in the design of high efficiency optoelectronic devices.
