▎ 摘　　要

NOVELTY - The absorber has a first quartz substrate (1) and a second quartz substrate (8) combined by a sealant to form a liquid crystal cell. A liquid crystal layer (5) is arranged between first and second quartz substrates. The liquid crystal layer is placed around first and second quartz substrates. A liquid crystal material is selected as a terahertz band large birefringence liquid crystal material. A Silica microsphere liner material and the second quartz substrate are placed into the liquid crystal box. A middle air layer is formed with the silica microsphere liner material. USE - Graphene-metamaterial based electric control liquid crystal tunable terahertz wave absorber. ADVANTAGE - The absorber has simple and efficient process, better electric field distribution and liquid crystal display control ability, and utilizes arbitrarily designed sub-wavelength unit array structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-metamaterial based electric control liquid crystal tunable terahertz wave absorber preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a graphene-metamaterial based electric control liquid crystal tunable terahertz wave absorber. Quartz substrates (1,8) Sub-wavelength metal unit array (2) Porous graphene layer (3) Photo-alignment layer (4) Liquid crystal layer (5)
