Scattering Reduction and Invisibility Condition in a Cylindrical Layered Graphenic Metamaterial

Plasmonic cloaking is one of the invisibility methods which is very attractive for researchers. Despite of non-perfect nature of this method, there are some advantages such as easier practical realization for it. In this paper, considering cylindrical layered metamaterial with composition of graphene and TiO2 layers, wave equation is solved for this structure analytically. After calculating scattering cross section, invisibility condition is investigated in the structure. Then, the effect of changing in some geometrical and physical parameters such as chemical potential, core radius and number of layers on invisibility condition is analyzed. Some numerical simulation using COMSOL approve the results.
