The invention relates to a wave absorbing material which comprises at least one material slice layer. Each material slice layer comprises three layers of substrates which are respectively a first substrate, a second substrate and a third substrate from top to bottom. Each substrate comprises at least one substrate unit, wherein a metal micro structure is attached to the surface of the substrate unit. The metal micro structure attached to the upper surfaces of the same substrate units of the first substrate are at least on hollow annular structure with the same size, and the sizes of hollow annular structures attached to at least two substrate units of the substrate unit of the first substrate are different. The metal micro structures attached to the upper surfaces of the substrate units of the second substrate are opening annular structures, and two ends of opening rings of the opening annular structures are respectively wound inwards to form two mutually-disjoint spiral structures. The metal micro structures attached to the upper surfaces of the substrate units of the third substrate are complementary with the metal micro structures attached to the substrate unit of the second substrate. The wave absorbing material of the structure has good wave absorbing performance.
Description
technical field [0001] The invention relates to a new type of artificial electromagnetic material, and more specifically relates 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 lo...
