Abstract

The invention discloses a metamaterial and a frequency adjustment method and apparatus therefor. The metamaterial comprises a substrate material, an electric controllable structural unit array and a variable capacitance diode, wherein the electric controllable structural unit array is arranged on the substrate material; the electric controllable structural unit array comprises multiple electric controllable structural units, wherein each electric controllable structural unit comprises an external metal structure and an internal metal structure; the internal metal structure and the external metal structure form an annular channel; and the variable capacitance diode is arranged in the channel of each electric controllable structural unit, and used for adjusting the working frequency of each electric controllable structural unit according to the voltages loaded at the two ends of the variable capacitance diode. By virtue of the metamaterial, the technical problem that the working frequency of the metamaterial cannot be adjusted quickly and accurately in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of control, in particular to a metamaterial and its frequency adjustment method and device. Background technique [0002] In the existing society, metamaterials have artificial composite structures with extraordinary physical properties that traditional natural materials do not possess. However, for metamaterials, their strange electromagnetic properties have a frequency band range. Beyond this range, this strange The electromagnetic properties will be weakened or even disappear. Therefore, relevant technical personnel began to study controllable metamaterials. In the existing research results, controllable metamaterials mainly include three categories: (1) mechanically controllable metamaterials; (2) loaded microwave switches; ( 3) Loading controllable materials (for example, ferrite, liquid crystal material, graphene, etc.). Among them, the mechanically controllable metamaterial has a relatively large volume and i...
