This article proposes a novel analytical model for the anisotropic\nmulti-layer structures containing magnetically biased graphene sheets. The\nmulti-layer structure is composed of various magnetic materials. An external\nmagnetic field is applied, normal to the structure surface. Each graphene\nsheet, with an anisotropic conductivity tensor, has been sandwiched between two\nadjacent magnetic materials. Our model is used to find the dispersion relation\nof the structure. Now, obtaining plasmonic features of the structure, such as\nthe effective index and propagation loss is straightforward. Four exemplary\nstructural variants have been investigated to show the richness of the proposed\ngeneral structure regarding the related specific plasmonic wave phenomena and\neffects. These aspects are essential to form our structural design platform to\npropose novel plasmonic devices such as biosensors, modulators, absorbers,\ntransparent electrodes, and tunable metamaterials in THz frequencies. A very\ngood agreement between the analytical and full-wave simulation results is seen.\n
