[0016] see figure 2 , the first embodiment of a wave absorbing device in the embodiment of the present invention includes:

[0017] The wave absorbing device includes a wave absorbing module 21 and an electromagnetic wave angle adjustment module 22, wherein the electromagnetic wave angle adjustment module 22 converts the spherical electromagnetic wave emitted by the point source into a plane electromagnetic wave, and the beams of the plane electromagnetic wave are parallel to each other, and the equiphase plane is a plane. The plane electromagnetic wave is incident on the wave absorbing module and absorbed by the wave absorbing module. The electromagnetic wave angle adjustment module includes at least one piece of non-uniform metamaterial. The refractive index of the non-uniform metamaterial gradually decreases from the center along the radial direction to form a circular distribution.

[0018] In this embodiment, by adding an electromagnetic wave angle adjustment module in t...

Abstract

The embodiment of the invention provides a wave-absorbing device which comprises a wave-absorbing module and an electromagnetic wave angle adjustment module, wherein the electromagnetic wave angle adjustment module is used for converting an electromagnetic wave emitted from a spherical electromagnetic wave, which is sent out by a point source, into a parallel electromagnetic wave; and the parallel electromagnetic wave is emitted to the wave-absorbing module and absorbed by the module. By using the wave-absorbing device, the electromagnetic wave sent out by the point source can be converted into a plane wave after passing through the electromagnetic wave angle adjustment module, and then the plane wave is vertically emitted to the wave-absorbing module, thereby forming an outstanding wave-absorbing effect to the electromagnetic wave sent out by the point source.

Description

【Technical field】 [0001] The invention relates to a wave absorbing device, in particular to a wave absorbing device capable of absorbing spherical electromagnetic waves emitted by a point source. 【Background technique】 [0002] Metamaterials refer to some artificial composite structures or composite materials with extraordinary physical properties that natural materials do not have; through the orderly design of the structure on the key physical scale of the material, it is possible to break through the limitations of some apparent natural laws and obtain Metamaterial capabilities beyond the ordinary properties inherent in nature. [0003] Metamaterials are composed of a dielectric substrate and multiple metal microstructures arranged on the substrate, which can provide various material properties that ordinary materials have and do not have. The size of a single metal microstructure is generally less than 1 / 10 of a wavelength, and it has an electric response and / or a magne...
