摘要

Graphene paves the way for the outstanding applications as it is one-atom thick and possesses perfect tunability properties. The main goal of this work is to study mode patterns of surface waves propagating in the graphene-based structures in the far-infrared region. Herein, we study a broad variety of graphene structures starting with the simplest gra-phene/dielectric interface guiding conventional surface plasmon polaritons (SPPs) and ending up with more complicated cases allowing to have a deeper insight into the complexity of the mode patterns tunability features provided by graphene paving the way for the hybridized waves. Thus, the hybridized surface-phonon-plasmon-polaritons (SPPPs) guided by graphene/LiF/glass compounds are theoretically studied. By constructing a het-erostructure comprising graphene and LiF one may benefit from the advantages of both, resulting in engineerable hybridized SPPPs propagating in both directions, i.e. either for-wardly or backwardly. Moreover, we conclude with presentation of the metamaterial composed of graphene and LiF building blocks allowing for an enhanced degree of freedom.
