Abstract

The invention relates to a wave absorbing material, comprising at least one material sheet, wherein each material sheet comprises three substrates which respectively are a first substrate, a second substrate and a third substrate from top to bottom; each substrate comprises at least one substrate unit; the upper surface of each substrate unit is attached with a metal microstructure; the metal microstructure attached on the upper surface of the first substrate is of a hollow circular structure with line width which is not completely equivalent; the metal microstructure attached on the upper surface of the substrate unit of the second substrate is at least two hollow rings or at least two hollow rings with openings, wherein the hollow rings or the hollow rings with openings have the same central point and different sizes; the metal microstructure attached on the upper surface of the substrate unit of the third substrate is complementary with the metal microstructure attached on the substrate unit of the second substrate. The wave absorbing material with the above structure has good wave absorbing property.

Description

technical field [0001] The invention relates to a new type of artificial electromagnetic material, more specifically, to a wave-absorbing material with better wave-absorbing performance. Background technique [0002] With the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing. At the airport, flights are delayed due to electromagnetic wave interference; in hospitals, mobile phones often interfere with the normal work of various electronic medical instruments. Therefore, controlling electromagnetic pollution and finding a material that can resist and weaken electromagnetic radiation—wave-absorbing materials have become a major topic in material science. [0003] Absorbing material refers to a class of materials that can effectively absorb the energy of electromagnetic waves incident on its surface. It converts incident electromagnetic waves into heat energy or other energy forms through various loss mechanis...
