▎ 摘　　要

NOVELTY - The material has a hyper-surface placed on a layer of the single- layer graphene. An end of the voltage device is connected with the single-layer graphene. Another end of the voltage device is covered with an ion gel, where the thickness of the ion gel is 20m. A pixel unit of hyper-surface is formed with a gradient phase structures, where the gradient phase structure encodes different target images using different frequencies and the pixel unit is a hyper-surface sub-wavelength magnitude. The pixel unit is fixed with a strip-shaped structure, a mouth-shaped structure and a U-shaped structure. USE - Graphene-based dynamic tunable optical holographic design material. ADVANTAGE - The material is convenient and practical, fills the blank in the field of hologram tunable optical holography, and has sub-wavelength level and compact structure, and realizes the miniaturization and integration of the optical device. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a graphene-based dynamic tunable optical holographic design material. '(Drawing includes non-English language text)'
