▎ 摘　　要

NOVELTY - The sheet has a main body provided with a two-sheet fused quartz substrate. An inner side of the substrate is fixed to a sub-wave length metal wire grid. A substrate emitting surface is connected with a porous graphite layer. A fused quartz base plate is linked to a liquid crystal box that is fixed between a metal wire grid and two light-alignment layers. The light-alignment layers are coated with liquid crystal material that is formed as terahertz electric control large birefringence liquid crystal material. An angle is formed in the wire grid for about 45 degrees along orientation direction. USE - Broadband adjustable liquid crystal porous graphene transparent terahertz wave sheet. ADVANTAGE - The sheet has wide range of applications, high transmission rate and large quantity. The sheet provides quick response and electric control double refraction characteristics. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a broadband adjustable liquid crystal porous graphene transparent terahertz wave sheet preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of a broadband adjustable liquid crystal porous graphene transparent terahertz wave sheet.
