▎ 摘  要

NOVELTY - Graphene-based artificial diffuse scattering control metasurface comprises a dielectric substrate (1), and a phase control unit (2) is arranged above the dielectric substrate. A resonant unit (3) is arranged under the dielectric substrate. An isolation plate (4) is arranged below the resonance unit (3). A grounding plate (5) is arranged below the isolation plate. USE - The metasurface is useful in selective electromagnetic stealth, antenna cover and Ultra wide-band (UWB) system. ADVANTAGE - The metasurface realizes the control of diffuse reflection frequency by changing the length of the resonant unit, is designed with conductive graphene macroscopic film as the conductor material, which has the characteristics of light weight, corrosion resistance, and environmentally friendly. The graphene frequency reconfigurable filter antenna has good filtering characteristics and harmonic suppression ability, and the potential to be applied to selective electromagnetic stealth, radome and ultra-wideband systems. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the structure of a graphene-based artificial diffuse scattering control metasurface. 1Dielectric substrate 2Phase control unit 3Resonance unit 4Isolation plate 5Grounding plate
