Abstract

The invention relates to a wave absorbing material comprising at least one material sheet layer; each material sheet layer comprises three layers of substrates; the substrates are respectively a first substrate, a second substrate and a third substrate from the upper side to the lower side; each layer of substrate comprises at least one substrate unit; a metal microstructure is attached on the upper surface of each substrate unit; the metal microstructure attached on the upper surface of the substrate unit of the first substrate is composed of a plurality of hollow-ring-shaped structures in nonidentical sizes, wherein the hollow-ring-shaped structures in the same size are arranged like a round array; the metal microstructures attached on the upper surface of the substrate unit of the second substrate is split-ring-shaped structures, wherein both ends of the a split ring respectively rotate inwards to form two mutually-disjointed spiral structures; and the metal microstructures attached on the upper surface of the substrate unit of the third substrate and the metal microstructures attached on the substrate unit of the second substrate are complementary. The wave absorbing material with the structure has better wave absorbing property at a low-frequency stage.

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 in the low-frequency band. 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 thr...
