▎ 摘　　要

NOVELTY - The structure has a dual-band plasmonic sensor fixed with a transparent substrate to emits light wave in a working band. A non-symmetrical metal graphene single-layer is arranged with the substrate and uniformly distributed with an asymmetric gold nano antenna array and a non-symmetrical metal medium layer. A structure size value of a gold nano-strip pair dimer is less than a wavelength value of the light wave in the working band. Periodic range of the asymmetric gold nano-antenna array is about 200-3000 mm. Length of gold nano-stripes is about 50-3000 mm. Width of the gold nano-stripes is about 50-1500 mm. Thickness of the gold nano-stripes is about 20-200 mm. USE - Waveband plasmon sensor based gold nanometer antenna/graphene structure. ADVANTAGE - The structure has wide range of application, and improves safety performance and environment monitoring quality and increases sensor sensitivity. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a waveband plasmon sensor based gold nanometer antenna/graphene structure.
