Abstract

The invention relates to a wave absorbing material which comprises at least one material sheet layer. Each material sheet layer comprises three layers of substrates which are the first substrate, the second substrate and the third substrate from top to bottom, each substrate comprises at least one substrate unit, and the upper surface of each substrate unit is provided with a metal microstructure in an attached mode. The metal microstructures attached to the upper surfaces of the substrate units of the first substrate are the same in size, and at least one of the metal microstructures is a hollow ring structure; the metal microstructures attached to the upper surfaces of the substrate units of the second substrate are hollow rings with at least two common central points and of different sizes or are hollow rings with openings; the metal microstructures attached to the upper surfaces of the substrate units of the third substrate are complementary to metal microstructures attached to the upper surfaces of the substrate units of the second substrate. The wave-absorbing material of the structure has good wave-absorbing performance on low-frequency stages.

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...
