Embodiment Construction

[0023] This embodiment provides a kind of absorbing material, such as figure 1 As shown, one artificial electromagnetic material sheet is included, and of course a plurality of artificial electromagnetic material sheets can be included. When there are multiple artificial electromagnetic material sheets, adjacent artificial electromagnetic material sheets can be It is assembled into a whole by means of mechanical connection, welding, or filling substances that can connect the two adjacent artificial electromagnetic material sheets. figure 1 The artificial electromagnetic material sheet shown in includes three substrates, and the three substrates are respectively the first substrate 1, the second substrate 2 and the third substrate 3 from top to bottom, and artificial microstructures are attached to each substrate, such as figure 1 As shown in 4, 5 and 6, the adjacent substrates are bonded together by an adhesive, of course, they can also be assembled together by mechanical conn...

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 include 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 size of each substrate unit and the size of the corresponding metal microstructure of the first substrate decrease gradually from one side to the other side opposite to the one side of the first substrate, and the corresponding artificial microstructure is a hollow ring structure; the metal microstructure attached to the upper surface of each substrate unit of the second substrate is of an open ring structure, and the two ends of the open ring are spirally wound inwards respectively to form two spiral structures which are not intersected with each other; the metal microstructure attached to the upper surface of each substrate unit of the third substrate is complementary to the metal microstructure attached to the upper surface of each substrate unit 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 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...
