▎ 摘　　要

NOVELTY - Nonlinear device based on graphene nonlinear ultra-surface for wavefront control, where the nonlinear device comprises a plurality of periodically distributed superstructure grating comprises a metal substrate. The metal substrate is provided with multiple grooves periodically distributed. The groove is filled with a medium layer. The medium layer is covered with a periodically distributed graphene belt. The graphene belt is respectively with independent voltage to control the chemical potential of the graphene conveyor, so as to realize the non-linear phase gradient. USE - Nonlinear device based on graphene nonlinear ultra-surface for wavefront control. Uses include but are not limited to beam splitters, holographic imaging, super-lenses, parity-related diffraction and angle asymmetric diffraction. ADVANTAGE - The device provides an improved diffraction law for nonlinear wavefront control, the law can break through NGSL limit for non-linear wave front control, realizes the multifunctional control of the non-linear wave, realizes the design of nonlinear device. The material of the metal base is gold, optical of characteristics is composed of Drude model obtain where fp=2069THz, 17.65THz and PMMA, and the dielectric constant is 2.25. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the nonlinear device based on graphene nonlinear ultra-surface for wavefront control.
