A modulation principle and method, the gate-voltage-controlled mode-guiding switching/mode-cutoff mechanism, is proposed and numerically investigated to achieve the modulation/attenuation function. The propagating attenuation of the graphene 2D waveguide as a function of the Fermi level of the cladd...
