Paper Abstract

The present work investigates the propagation properties of the surface plasmon polariton wave supported on graphene surface over an anisotropic substrate at far-infrared frequencies. Initially, the surface wave’s propagation on isotropic media substrate is studied and verified with the theoretical estimation, including the noteworthy epsilon-near-zero case. Moreover, after utilizing theoretical substrate media and examining anisotropy relative to the normal to graphene’s surface, direction, the anisotropy is enforced to the tangential direction revealing the significant influence of the substrate on the surface wave that is propagating on graphene. Additionally, the more realistic implementation with graphene’s substrate consisting of metamaterial resonators is thoroughly investigated. Numerical results are extracted through a reliable finite-difference time-domain (FDTD) algorithm, focalising, mainly, on the wavelength of graphene’s surface wave.
