Problems solved by technology

As a fixed substrate for artificial microstructures, the existing dielectric substrate has uniform permittivity and permeability as a whole, so it does not produce a unique response to electric or magnetic fields, that is, for the entire metamaterial, the dielectric substrate also Does not have electromagnetic modulation function

Abstract

The invention provides a preparation method of a meta-material dielectric substrate. Organic high molecular solids with different dielectric constants are formed in different regions of a porous material substrate with a centrifugal method, and non-uniform dielectric constant distribution of the meta-material dielectric substrate is realized, so that the meta-material dielectric substrate has richer electromagnetic modulating functions, and the functional applications of a meta-material are expanded.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a process for preparing 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. Advanced organic resin substrates, such as FR4, TP1, etc., generally adopt the existing PCB processing technology. [0003] For metamaterials, since the multiple artificial microstructures arrayed on the dielectric substrate have specific electromagnetic properties, they can generate electromagnetic responses to electric or magnetic fields. Therefore, through the precise design and control of the structure and arrangement of the artificial micr...
