Problems solved by technology
In theory, we can realize metamaterials with a dielectric constant in any range on metamaterials. However, due to the limitations of the size of the metamaterial substrate and the manufacturing process, it is difficult for the existing metamaterials to achieve the same metamaterial. The upper dielectric constant changes continuously in a large range, and the dielectric constant of the metamaterials in the prior art can only be continuous in a small range, so that in many applications, the metamaterials in the prior art cannot meet the needs

Embodiment Construction
[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] figure 1 Shown is a metamaterial according to the invention comprising at least one metamaterial sheet 100 comprising a plurality of metamaterial sub-sheets S1, S2, . . . , Sn, where n is positive Integer and greater than or equal to 3. Each metamaterial sub-sheet includes a base material and an artificial microstructure attached to the base material, wherein the dielectric constant ranges of multiple metamaterial sub-sheets S1, S2, ..., Sn-1, and Sn are respectively (ε1, ε1'), (ε2, ε2'), ..., (εn-1, εn-1'), (εn, εn'), where ε1<ε1', ε2<ε2',... , εn-1<εn-1', εn<εn', and ε1<ε2<=ε1', ε2<ε3<=ε2', ..., εn-1<εn<=εn-1'. Moreover, at least two different materials are selected for the plurality of substrates included in the plurality of metamaterial sub-sheets. In the embodiment of the present invention, at least two kinds of materials from ceramics...

The invention provides a metamaterial. The metamaterial comprises a plurality of metamaterial sub-layers, wherein each of the metamaterial sub-layers has a dielectric constant change range; and the dielectric constant change range of one of the metamaterial sub-layers partially overlaps with the dielectric constant change range of at least one of the other metamaterial sub-layers. The metamaterial has a dielectric constant change range continuously changing in a large range, and has a simplified preparation process, so the process for preparing the metamaterial with above characteristic is simple, and the dielectric constant change range of the metamaterial can be designed according to a concrete application environment. The process which is simple is easy to realize.
Description
【Technical field】 [0001] The invention relates to a metamaterial, in particular to a metamaterial whose dielectric constant changes gradually within a large range. 【Background technique】 [0002] Metamaterial is a new academic vocabulary in the field of physics in the 21st century, and it often appears in various scientific literatures in recent years. Three important characteristics of metamaterials include: [0003] (1) Metamaterials are usually composite materials with novel artificial structures; [0004] (2) Metamaterials have extraordinary physical properties (such properties are often not available in natural materials); [0005] (3) The properties of metamaterials are often not determined by the intrinsic properties of the constituent materials, but mainly by the artificial structures in them. [0006] Metamaterials are materials that use artificial microstructures as basic units and are spatially arranged in a specific way, and this material is a new type of mate...
