Problems solved by technology

[0003] In order to make different regions of the dielectric substrate have a predetermined dielectric constant distribution, the dielectric substrate can be made to include a plurality of substrate units, and a non-uniform distribution of the dielectric constant can be realized by selecting a suitable material for each substrate unit. However, affected by the range of material selection, the material selected for each substrate unit cannot meet the predetermined requirements well, and its dielectric constant is not easy to control

Abstract

The invention provides a method for preparing a medium substrate with heterogeneous dielectric constants and a meta material; the method allows random and flexible design of the dielectric constants of the medium substrate as a whole, and thus provides the meta material with more abundant functional applications. Through the flexible design of the dielectric constants, impedance matching of the artificial microstructure in the meta material is realized, and the method also has the advantages of reducing microwave dielectric loss of the medium substrate.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a dielectric substrate of a metamaterial. 【Background technique】 [0002] Metamaterials are generally composed of multiple metamaterial functional plates stacked or combined according to other regular arrays. The metamaterial functional plate includes a dielectric substrate and multiple artificial microstructures arrayed on the dielectric substrate. The existing metamaterial dielectric substrate is a uniform material. Organic or inorganic substrates, such as FR4, TP1, etc. Multiple artificial microstructures arrayed on a dielectric substrate have specific electromagnetic properties and can generate electromagnetic responses to electric or magnetic fields. By precisely designing and controlling the structure and arrangement of the artificial microstructures, metamaterials can exhibit various Electromagnetic properties that ordinary materials do not have, such as the ability to conv...
