Metamaterials and their processing methods

Abstract

The invention discloses a metamaterial and a processing method thereof. The method comprises the following steps: processing the surface of a metamaterial functional layer to increase surface binding force, wherein the metamaterial functional layer comprises a dielectric layer and a conductive geometric structure located on the dielectric layer; and binding the surface-treated metamaterial functional layer with at least one layer of a composite material. According to the invention, through roughening process of the functional layer, the contact area between the functional layer and the composite material is increased, so the surface binding force between the functional layer and the composite material layer is effectively increased; the surface of the finished metamaterial product can be more smooth; flexural deflection and layering are avoided; and the yield rate of superior products is effectively improved.

Description

technical field [0001] The present invention relates to the field of materials, and in particular, to a metamaterial and a processing method thereof. Background technique [0002] Metamaterials are generally composed of dielectric materials and conductive geometric structures, wherein the conductive geometric structures are arranged in an array along a certain plane or curved surface, and an array is formed as a layer. In the usual metamaterial design, there can be more than one layer of microstructures, and the multilayer microstructures are scattered in the dielectric material according to certain rules, and the multilayer microstructures do not intersect each other. [0003] Fiber-reinforced resin-based composites have excellent mechanical properties, and their dielectric properties can also be adjusted within a certain range according to design requirements, so they are often used as dielectric materials to form metamaterials. [0004] However, the insufficient adhesion...

Problems solved by technology

[0004] However, the insufficient adhesion of many composite materials such as fiber-reinforced resin-based composites to conductive geometries in the related art not only leads to delamination in the processed metamaterial, but also easily leads to the deformation of the metamaterial.

[0005] For the above-mentioned problems in related technologies, no effective solution has been proposed yet
