Problems solved by technology

Although flat metamaterials bring the advantages of small size and thin thickness, they limit the application range of metamaterials.
[0004] When the metamaterial needs to be made into a curved surface, the microstructure processing technology of the curved surface is difficult and the accuracy is not high. The specific implementation method is: using the laser probe exposure imaging method to etch the microstructure one by one
The processing cost and process precision control cost of this method are high

Abstract

The invention discloses a three-dimensional structure metamaterial which comprises at least one layer of forming base material and at least one flexible function layer arranged on the surface of the forming base material. Each flexible function layer comprises a flexible substrate formed by at least one flexible sub-substrate and a plurality of manmade micro-structures corresponding to electromagnetic waves and arranged on the surface of each flexible sub-substrate. The three-dimensional structure metamaterial has an electromagnetic wave modulation function. The three-dimensional structure metamaterial is simple in manufacturing process and low in processing cost, process precision is controlled simply, and the three-dimensional structure metamaterial can replace various structure parts provided with complex curved surfaces and needing to have a certain electromagnetic modulation functions and can also be attached to various structure parts provided with the complex curved surfaces to achieve the required electromagnetic modulation functions. Besides, the three-dimensional structure metamaterial has good electromagnetic response and wide application range in a curved surface expanding and electromagnetic partition mode.

Description

technical field [0001] The invention relates to a supermaterial, in particular to a three-dimensional structure supermaterial. Background technique [0002] Metamaterial is a new type of artificial material that has been developed in the past ten years to modulate electromagnetic waves. The basic principle is to artificially design the microstructure (or artificial "atom") of the material, so that such a microstructure has specific electromagnetic properties. Therefore, the material composed of a large number of microstructures can have the desired electromagnetic function macroscopically. Different from traditional material technology, which develops electromagnetic utilization methods based on the natural properties of existing materials in nature, metamaterial technology artificially designs the properties of materials and manufactures materials according to needs. Metamaterials are generally composed of a certain number of artificial microstructures attached to a substr...
