The simulated transmission spectra (a) and the calculated group delay (b) with different Fermi levels of graphene. The inset in (a) shows the evolution of the transmission spectrum versus Fermi energy and frequency. (c)–(f) The surface charge density distributions when the Fermi energy of graphene increases from 0.0 eV to 0.3 eV with a step of 0.1 eV.
