Embodiment Construction

[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the drawings and specific embodiments are only exemplary, and should not be construed as limiting the protection scope of the present invention.

[0054] As a multilayer artificial material composed of a dielectric substrate and an artificial conductive geometric structure arranged on the substrate, metamaterials have some extraordinary physical properties that natural materials do not possess. The artificial conductive geometric structure has electrical and magnetic responses to external electric and magnetic fields on the scale of 1 / 5 to 1 / 10 wavelength, so that the metamaterials exhibit equivalent permittivity and equivalent magnetic permeability as a whole Rate. By designing the pattern and / or size of each conductive geometric structure and arranging the conductive geometric structu...

Abstract

The invention provides a super material. The super material includes a plurality of electric conduction geometric structure layers; each electric conduction geometric structure layer in the plurality of electric conduction geometric structure layers comprises a substrate and a plurality of electric conduction geometric structures arranged on the substrate; intervals between adjacent conductive geometric structures on each electric conduction geometric structure layer are equal; and intervals between adjacent electric conduction geometric structures on at least one electric conduction geometric structure layer are not equal to intervals between adjacent electric conduction geometric structures on other electric conduction geometric structure layers. The super material provided by the invention may include a plurality of electric conduction geometric structure layers; each electric conduction geometric structure layer in the plurality of electric conduction geometric structure layers comprises a substrate and a plurality of electric conduction geometric structures arranged on the substrate; and intervals between adjacent electric conduction geometric structures on at least one electric conduction geometric structure layer in the plurality of electric conduction geometric structure layers are not equal.

Description

technical field [0001] The invention relates to a wave-absorbing material, in particular to a wave-absorbing metamaterial. Background technique [0002] Absorbing materials refer to a class of materials that can absorb electromagnetic wave energy projected onto its surface. Coating wave-absorbing materials on aircraft, missiles and other weapons and military facilities can absorb reconnaissance waves, attenuate reflected signals, and achieve the stealth effect on radars, thereby breaking through the defense zone of enemy radars. In the increasingly important stealth technology, electromagnetic wave absorbing materials have become the magic weapon and "secret weapon" in electronic countermeasures in modern military. In addition, with the development of modern science and technology, the impact of electromagnetic radiation on the environment is increasing day by day, and the harm to human health has attracted more and more attention. Absorbing materials can also play a huge ...
