▎ 摘　　要

NOVELTY - The polarizer has a dielectric layer that is provided between each of the two adjacent graphene layers (1). The holes (5) on the graphene layer coincides with the holes on the dielectric layer. The holes of the graphene layers and the dielectric layers are arrayed. The even graphene layer is connected to one electrode. The odd graphene layer is connected to other electrode. The voltage regulation is achieved by loading the voltage on both electrodes. A cross-sectional area of the hole of the graphene layer is greater than an area of the terahertz light spot. USE - Graphene-based electronically controlled terahertz polarizer for use in broadband communication, radio detection and ranging, electronic warfare, electromagnetic weapons, astronomy, nondestructive testing, medical imaging and safety inspection applications. ADVANTAGE - The polarizing plate can be prepared by the multilayer film structure through the structural parameters of the grid such as the width of the grid and the space cycle. The number of graphene layers controls the response frequency band, degree of polarization and other performance parameters through voltage regulation. The degree of polarization can be actively controlled through the terahertz wave. The different polarization direction of the terahertz wave selective modulation function can be achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of using the graphene-based electronically controlled terahertz polarizer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a polarizing plate structure. Graphene layer (1) Hole (5)
