摘要: The excitation and absorption properties of grating coupled graphene surface plasmons were studied. It was found that whether a mode can be excited is mainly determined by the frequency incident light duty ratio gratings. In structure consisting bilayer, blueshift existed when distance between neighbor layer decreased gradually. graphene-grating multilayer structures, strong (approximately 90% at maximum) in near-THz range.
