Problems solved by technology

Traditional absorbing materials are deficient in anti-matching design, so that all electromagnetic energy cannot enter the interior of the absorbing medium, resulting in a large amount of electromagnetic energy being reflected and reducing its absorbing performance
And the materials of its honeycomb structure are mostly conventional absorbing materials such as carbon nanotubes or ferrites. Although the technology is mature, they also have corresponding shortcomings. For example, ferrite has shortcomings such as high density and poor high-temperature characteristics, while carbon nanotubes Has certain toxicity to organisms and is subject to certain restrictions in the application field

Abstract

The invention belongs to the technical field of stealth materials and particularly relates to a wave-absorbing material with a regular honeycomb 10-degree structure. The material comprises a wave-transmitting layer, a wave-absorbing layer, and a reflecting layer which are stacked in sequence from top to bottom, the wave-transmitting layer is made of a composite fiber material and has a first preset size, the wave absorbing layer is made of a magnetic micron wire material, is of a regular honeycomb 10-degree structure and has a second preset size; and the reflecting layer is made of metal and has a third preset size. The invention discloses the wave-absorbing material with the regular honeycomb 10-degree structure, a regular honeycomb-shaped wave-absorbing structure of an unconventional structure of a novel wave-absorbing medium is adopted; impedance matching is achieved by adding the wave-transparent layer, electromagnetic energy reflection is reduced, incident electromagnetic wave polarization and magnetization are caused by fully utilizing the structure, a good absorption effect on 2GHz-18GHz electromagnetic waves is achieved through the wave-absorbing medium loss effect, and theelectromagnetic compatibility shielding or stealth effect is achieved.

Description

technical field [0001] The application belongs to the technical field of stealth materials, and in particular relates to a wave-absorbing material with a positive honeycomb 10° structure. Background technique [0002] At present, honeycomb absorbing materials with honeycomb structure adopt a positive honeycomb structure, which does not cause the maximum loss of incident electromagnetic waves, and its stealth or shielding properties are limited. Traditional absorbing materials have deficiencies in the anti-matching design, which prevents all electromagnetic energy from entering the absorbing medium, causing a large amount of electromagnetic energy to be reflected and reducing its absorbing performance. And the materials of its honeycomb structure are mostly conventional absorbing materials such as carbon nanotubes or ferrites. Although the technology is mature, they also have corresponding shortcomings. For example, ferrite has shortcomings such as high density and poor high-...
