Problems solved by technology

[0003] Existing metamaterials are generally prepared by arraying metal microstructures on organic resin substrates. The dielectric substrate uses organic resin materials, so the overall dielectric constant is small, which cannot meet the application requirements.
At the same time, the artificial microstructure of metal materials has the disadvantages of easy detachment and complex structure.
The existing metamaterials with metal microstructures arrayed on organic resin substrates are suitable for electromagnetic waves in the microwave frequency band, but have particularly large losses for high frequencies such as infrared and visible light bands.

Embodiment 1

[0025] A method for preparing a metamaterial functional board. For the flow chart of the preparation method in this embodiment, please refer to the attached figure 1 , including the following steps:

[0026] a. Mix strontium barium titanate powder and magnesium oxide powder uniformly in different proportions, and then sinter at a high temperature of 1300-1400°C to obtain strontium barium titanate magnesium oxide ceramic materials with different dielectric constants;

[0027] b. Measure the dielectric constant of strontium barium titanate magnesia ceramic material to obtain the relationship between the dielectric constant and the ratio of strontium barium titanate and magnesium oxide. Since the ratio of strontium barium titanate powder and magnesium oxide powder is different, high temperature The dielectric constant of the strontium barium titanate magnesia ceramic material obtained by sintering is different, so the corresponding relationship of the dielectric constant relative...

Embodiment 2

[0035] A method for preparing a metamaterial functional board. For the flow chart of the preparation method in this embodiment, please refer to the attached figure 2 , including the following steps:

[0036] a. Mix strontium barium titanate powder and silicon dioxide powder in different proportions evenly, and then sinter at a high temperature of 1300-1400°C to obtain strontium barium titanate silica ceramic materials with different dielectric constants. The ratio of strontium to barium in the barium strontium oxide powder makes the barium strontium titanate powder itself have different dielectric constants;

[0037] b. Measure the dielectric constant of barium strontium titanate magnesia ceramic material, obtain the relation of dielectric constant relative to the ratio of strontium barium titanate and silicon dioxide, because the ratio of strontium barium titanate powder and silicon dioxide powder is different , the dielectric constant of the strontium barium titanate silic...

Abstract

The invention provides a metamaterial and a method for producing a metamaterial function board. By utilizing special property of a dielectric constant of a barium strontium titanate non-ferroelectric ceramic material, the dielectric constant of the barium strontium titanate non-ferroelectric ceramic material prepared from barium strontium titanate and non-ferroelectric is accurately controlled through changing the proportion of the strontium titanate barium to the non-ferroelectric, so as to prepare an artificial microstructure on a ceramic substrate. According to the metamaterial produced byusing the method disclosed by the invention, the dielectric substrate and the artificial microstructure are both made of a ceramic material; and on one hand, the defects of small whole dielectric constant and easiness in dropping of the conventional metamaterial are overcome, and on the other hand, the dielectric constant of the artificial microstructure can be accurately controlled rather than being controlled only by the complex structure design of the artificial microstructure.

Description

【Technical field】 [0001] The invention relates to the field of supermaterials, in particular to the selection of artificial microstructures of supermaterials. 【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, such as FR4, TP1 and so on. 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 c...
