▎ 摘　　要

NOVELTY - Dual-spectrum dynamic stealth material based on layered design, comprises a middle infrared phase change grating layer, an intermediate dielectric transition layer and a microwave impedance matching layer stacked sequentially from top to bottom. The middle infrared phase change grating layer is a square protrusion periodically arranged on the upper surface of the intermediate medium transition layer for the absorption of infrared light. The intermediate dielectric layer is used to realize the transition from infrared spectrum modulation to microwave spectrum modulation, and is arranged between the middle infrared phase change grating layer and the microwave impedance matching layer. The material of the microwave reflection layer is a metal material, and the square resistance of the graphene film is regulated by the grid voltage to realize the regulation of the microwave absorption spectrum. USE - Used as dual-spectrum dynamic stealth material based on layered design. ADVANTAGE - The stealth material: is economical; has strong adaptability; and can realize the discrete dynamic control of different spectra. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the dual-spectrum dynamic stealth material based on layered design.
