▎ 摘　　要

NOVELTY - The structure has a metal medium elliptical cavity, graphene strips and a filling medium. The metal medium dielectric elliptical cavity is an array structure. The top and bottom of the metal dielectric elliptical cavity are flat. The distance between the top and the bottom of the metal dielectric elliptical cavity is equal. The metal medium elliptical cavity is provided with a filling medium. The graphene nanostrip array is laid flat on top of the filling medium. The construction material of the metal cavity shell can be selected from one of gold, silver, platinum, and titanium. USE - Enhanced graphene absorption structure based on metal medium elliptical cavity. ADVANTAGE - The absorption of graphene strips is provided with broad spectrum, strong absorption. The structure is applied to high-performance graphene optoelectronic devices in the mid-infrared band. The structure uses the two-dimensional thin film material graphene which is provided with characteristics of fast response and adjustable response and can be applied in micro-nano optics and integrated optics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphene absorbing structure based on metal dielectric elliptical cavity. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the orthogonal plane of the graphene absorption structure based on the metal dielectric elliptical cavity.
