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 relates to an inhomogeneous dielectric substrate made of metamaterials and a preparation method for the same. Prepregs with different dielectric constants are prepared and integrally pressed with a bottom plate by a hot-pressing method, so that the dielectric substrate made of the metamaterials is formed, wherein the dielectric substrate has different dielectric constants. The dielectric substrate made of the metamaterials has a specific electromagnetic modulation function, and function application of the metamaterials is expanded.

Description

【Technical field】 [0001] The invention relates to the field of metamaterials, in particular to a metamaterial heterogeneous dielectric substrate and a preparation method thereof. 【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 t...
