Herein, we deal with the propagation of surface plasmon polaritons at the interface of metal-free metamaterial with anisotropic inclusions. The anisotropy effect of conventional and well-known nanostructured metamaterial combined of alternating layers is enhanced by employing anisotropic semiconductor sheets into the structure. The former provides a fertile ground for a wide range of tunability features with no needs of changing the geometry of the structure. Moreover, the current approach stands for as a perfect tool aiming to control propagation length of surface plasmon polaritons.
