Wave absorbing material

Abstract

The invention discloses a wave absorbing material which comprises first and second capacitor and resistor hybrid layers which are arranged in front of a target object. The first capacitor and resistor hybrid layer is composed of a number of first unit structures. Each first unit structure comprises first, second, third and fourth basic units. The first basic unit comprises a first branch, a second branch and a third branch, wherein the second branch and the third branch vertically extend upward from both ends of the first branch. The first basic unit is respectively rotated by the degrees of 90, 180 and 270 to acquire second, third and fourth basic units. The second capacitor and resistor hybrid layer is composed of a number of second unit structures. The second unit structure and the first unit structure differ in that a number of fourth branches are arranged with equal spacing between a second branch and a third branch of the second unit structure. According to the invention, by arranging the capacitor and resistor hybrid layers of special structure, the effect of broadband and efficient electromagnetic wave absorbing can be realized.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a wave-absorbing material. Background technique [0002] With the rapid development of science and technology, there are more and more various technologies and products that use electromagnetic waves as the medium, and the impact of electromagnetic radiation on the environment is also increasing. For example, radio waves may cause interference to the airport environment, causing aircraft flights to fail to take off normally; mobile phones may interfere with the work of various precision electronic medical devices; even ordinary computers will radiate electromagnetic waves carrying information, which may It is received and reproduced kilometers away, resulting in the leakage of national defense, political, economic, technological and other intelligence. Therefore, controlling electromagnetic pollution and finding a material that can resist and weaken electromagnetic radiation—w...

Problems solved by technology

[0004] The existing wave-absorbing materials make use of the absorption properties of each material for electromagnetic waves. By designing the components of different materials, the mixed materials have wave-absorbing properties. The design of such materials is complicated and does not have large-scale promotion. The mechanical properties of the material are limited by the mechanical properties of the material itself, which cannot meet the needs of special occasions
