Problems solved by technology

[0003] Existing wave-absorbing materials use the absorption properties of each material to absorb electromagnetic waves, and design the components of different materials to make the mixed materials have specific wave-absorbing characteristics. The design of such materials is complex and does not have large-scale promotion, and absorbs electromagnetic waves The frequency band is narrow, which cannot meet the broadband absorbing effect. At the same time, the mechanical properties of this type of material are limited by the mechanical properties of the material itself, which cannot meet the needs of special occasions.

Embodiment Construction

[0026] Several preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention is not limited to these embodiments. The present invention covers any alternatives, modifications, equivalent methods and solutions made within the spirit and scope of the present invention.

[0027] In order for the public to have a thorough understanding of the present invention, specific details are described in the following preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0028] Light, as a kind of electromagnetic wave, when passing through glass, because the wavelength of light is much larger than the size of the atom, we can use the finishing parameters of the glass, such as the refractive index, rather than the detailed parameters of the atoms that make up the glass. The response of glass to light...

Abstract

The invention provides a wave-absorbing metamaterial which comprises a first substrate and a plurality of second substrates, wherein the first substrate and a plurality of second substrates are arranged in order in the direction of electromagnetic wave propagation. A reflection plate is arranged an outer surface of the first substrate. A circuit layer is arranged on the other outer surface or in the first substrate. A conductive geometrical structure layer is arranged between two adjacent second substrates. According to the invention, the metamaterial principle and the principle of circuit screen wave-absorbing are combined to design the broadband wave-absorbing metamaterial, and a broadband wave-absorbing metamaterial effect is realized through the multi-layer substrate setting.

Description

Technical field [0001] The invention relates to a material, and more specifically to a wave absorbing metamaterial and a wave absorbing device. Background technique [0002] With the rapid development of science and technology, there are more and more technologies and products using electromagnetic waves as the medium, and the impact of electromagnetic wave radiation on the environment is also increasing. For example, radio waves may cause interference to the airport environment, causing aircraft flights to fail to take off normally; mobile phones may interfere with the work of various sophisticated electronic medical devices; even ordinary computers may also emit electromagnetic waves that carry information. It was received and valued more than one kilometer away, causing the leakage of intelligence in defense, politics, economy, science and technology. Therefore, the treatment of electromagnetic pollution and the search for a material that can withstand and weaken electromagne...
