Manufacture method of dielectric substrate and metamaterial

Abstract

The invention provides a manufacture method of a dielectric substrate and a metamaterial. The manufactured metamaterial comprises the dielectric substrate and a plurality of artificial micro-structures arrayed on the dielectric substrate, the dielectric substrate is compounded of organic resin substrates and porous substrate materials, and the porous substrate materials have evenly-distributed nanometer through holes and meso pore structures. By using the metamaterial manufactured by the manufacture method of the dielectric substrate, the dielectric substrate is formed by compounding the organic resin substrates and the porous substrate materials, and the porous substrate materials have the evenly-distributed nanometer through holes and the meso pore structures. Due to the nanometer through holes and the meso pore structures, the dielectric substrate seems to be filled with air, but the dielectric constant of the air is about 1 and is greatly lower than that of the organic resin substrates. Therefore, the dielectric constant of the whole dielectric substrate is reduced, some specific application requirements can be met, and the organic resin substrates have excellent mechanical property and can meet various application occasions of the metamateiral.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to the preparation technology of metamaterial dielectric substrate materials. 【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, the limitation of some apparent natural laws can be broken through, so as to obtain the supernormal material function beyond the ordinary nature inherent in nature. The properties and functions of metamaterials mainly come from their internal structures rather than the materials that make them up, so a lot of research work has been done to design and synthesize metamaterials. In 2000, Smith et al. of the University of California pointed out that the composite structure of periodically arranged metal wires and split-ring resonators (SRR...

AI Technical Summary

Problems solved by technology

[0004] The existing artificial microstructures of metamaterials are generally made of metal materials, while the dielectric substrates generally use organic resin substrates. The dielectric constant of the dielectric substrate is limited to a fixed range. For some applications of metamaterials, lower dielectric constants are required. Constant dielectric substrate, in order to obtain good mechanical properties and meet the requirements of dielectric constant, none of the existing substrate materials can meet the requirements at the same time, which has become a technical problem to be solved urgently in the prior art
