(color online) (a) Schematic of the THz wave transfer between two graphene-based HMMs separated by a vacuum gap D. (b) The real part of the effective permittivities parallel (ε_‖) and perpendicular (ε_⊥) to the surface of graphene as a function of frequency. The width of Si is d = 50 nm, and the chemical potential of graphene is μ = 0.1 eV. (c) Variation of the real part of ε_‖ with frequency for different chemical potentials with d = 50 nm. (d) Variation of the real part of ε_⊥ with frequency for different thickness with μ = 0.1 eV.
