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.

本文首次研究了在介质中嵌入的石墨烯带的三维周期性结构中的等离振子-极化子的光谱，对于固定的载流子浓度，它对带宽度，界面距离和带周期的影响被显示。与石墨烯带的单层周期性结构相比，出现了明显的差异。此外，总是存在匹配点，在该匹配点处，等离子体激元的频率和电磁辐射的频率相同。该研究提高了我们在石墨烯中的等离激元动力学的基础知识，对于设计高效光电器件非常重要。
