The effect of the Fermi level of graphene on the absorption. (a) Calculated absorption as a function of frequency and Fermi level E F . (b) The absorption spectrum for E F = 0.0 eV under normal incident wave with the electric field parallel to x-axis. (c) Magnetic field amplitude patterns on the central cutting x-y plane of the dielectric cylinder for E F = 0.0 eV at 2.64 THz. (d) Magnetic field amplitude patterns on the central cutting y-z plane for E F = 0.0 eV at 2.64 THz.
