Problems solved by technology

[0005] Traditional structural absorbing composite materials rely on the electromagnetic loss of the matrix material (dielectric parameters and imaginary parts of magnetic permeability), so that the weight and thickness of the structure cannot meet the constraints of the aircraft structure and skin (the thickness often needs to be less than 1mm, and the structure less dense than aluminum or carbon fiber composite skins)

Embodiment Construction

[0039] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0040] Metamaterials composed of a dielectric substrate and artificial conductive geometric structures disposed on the substrate provide a direction for realizing high beam deflection rate, small volume, and simple structure of the skin material.

[0041] As an artificial material composed of a dielectric substrate and artificial microstructures disposed on the substrate, such as conductive geometric structures, metamaterials have some extraordinary physical properties that natural materials do not possess. The artificial conductive geometric structure has electrical and magnetic responses to external electric and magnetic fields on the scale ...

Abstract

The invention provides a metamaterial, a skin, and an aircraft. The metamaterial comprises a dielectric substrate, a metal backboard arranged at the backside of the dielectric substrate, and a plurality of conductive geometric structures arranged on the front surface of the dielectric substrate along the first direction and the second direction, each conductive geometric structure is an internal and external nested structure, the plurality of conductive geometric structures are divided into a plurality of conductive geometric structure groups, and in each conductive geometric structure group, dimension parameters of each conductive geometric structure are gradually changed at least in one direction of the first direction or the second direction.

Description

technical field [0001] The invention relates to the field of functional materials, in particular to a supermaterial, a skin and an aircraft including the skin. Background technique [0002] Modern detection and guidance technologies such as radar, millimeter wave, infrared, laser, multispectral and acoustic waves are widely used in national defense systems, posing a great threat to the survival of aircraft, ships, tanks and other equipment. [0003] As an effective means to improve the survival and penetration capabilities of national defense equipment, improve the stealth capability of equipment, and improve the overall combat effectiveness, microwave-absorbing material technology has been highly valued by the world's major powers. However, the traditional single wave-absorbing coating has limitations such as limited wave-absorbing frequency band, low efficiency, large weight, and poor temperature resistance, which cannot meet the requirements of modern equipment for the in...
