Abstract

Embodiments of the invention provide a preparation method of a metamaterial. The method comprises the following steps: adding a liquid-state high-molecular material in a mold and heating and curing to a viscous flow state so as to obtain a first flaky sheet material; aligning and pasting a first PCB possessing a metal microstructure array on the first flaky sheet material; further adding the liquid-state high-molecular material in the mold and heating and curing to the viscous flow state, and forming a second flaky sheet material on the first PCB; aligning and pasting a second PCB possessing the metal microstructure array on the second flaky sheet material. The embodiments of the invention also provide the metamaterial prepared by using the above preparation method. By using the method of the invention, malposition of the metal microstructure array on the PCB can be modified. Therefore, a preparation risk can be reduced and metamaterial quality can be guaranteed.

Description

【Technical field】 [0001] The invention relates to the technical field of artificial composite materials, in particular to a method for preparing a supermaterial and the supermaterial. 【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 processing of metamaterials is mainly to stack PCB boards with metal microstructure arrays, and fill other media between the layers. In the process of stacking PCB boards with metal microstructure arrays, it is necessary to align each layer of boards, and it is necessary to align the metal microstructure arrays of different PCB board layers. [0003] In t...
