Embodiment Construction

[0023] The invention provides a wave-transparent metamaterial, which includes a first substrate made of non-metallic material and a plurality of artificial microstructures arrayed on the surface of the first substrate. The artificial microstructure is a hollow cross-shaped structure. There are many choices of materials for manufacturing substrates, such as ceramics, FR4, F4B (polytetrafluoroethylene), HDPE (high density polyethylene, High Density Polyethylene), ABS (Acrylonitrile Butadiene Styrene, acrylonitrile-butadiene-styrene) , ferroelectric materials, or ferromagnetic materials.

[0024] Artificial microstructures are planar structures made of conductive materials with certain geometric patterns. The conductive material here can be metal materials with good electrical conductivity such as gold, silver, and copper, or an alloy material whose main component is one or two of gold, silver, and copper, or carbon nanotubes, aluminum-doped oxides, etc. Conductive non-metallic ...

Abstract

The invention relates to a wave-transparent meta-material. The wave-transparent meta-material comprises a first substrate and a plurality of artificial microstructures, wherein the first substrate is made of a nonmetallic material; the artificial microstructures are arrayed on the surface of the first substrate; each artificial microstructure is of a hollow cross-shaped structure. By specifically designing the shape of each artificial microstructure, the artificial microstructures have good wave-transparent response to an electromagnetic wave with a wider band. Within 7-18GHZ, the insertion loss of the wave-transparent meta-material can be controlled within minus 1dB.

Description

technical field [0001] The present invention relates to metamaterial technology, more specifically, to a wave-transparent metamaterial. Background technique [0002] Metamaterials refer to artificial composite structures or composite materials that have some extraordinary physical properties that natural materials do not have. The electromagnetic parameters of materials can be arbitrarily designed by using metamaterials, so that metamaterials have electromagnetic effects such as ultra-high dielectric constant, negative magnetic permeability, absorption of electromagnetic waves, and deflection of electromagnetic waves. Metamaterials can break through the limitations of some apparent natural laws through the orderly design of the structure on the key physical scale of the material, so as to obtain the supernormal material functions beyond the ordinary properties inherent in nature. [0003] Existing metamaterial technologies cannot achieve wide-band wave transmission, which l...
