Embodiment 1

[0032] When artificial microstructures such as Figure 5 As shown, a1=2.8 mm, a2=2.4 mm, a3=2 mm, a4=3 mm, a5=0.1 mm, the artificial microstructure 4 is as Figure 4 As shown, c1=c2=2.89 mm, c3=0.184 mm, c4=0.75 mm, such as image 3 For the substrate unit shown, d1=4 mm, d2=8 mm, the simulation diagram obtained by using the above parameters is as follows Figure 6 shown by Figure 6 The solid line in the figure shows that the dielectric constant characteristic of this material has the characteristics of multi-resonance, and the dielectric constant remains unchanged and is 20 in the frequency band (0GHz~8GHz). It can be seen that this material has a wide frequency and high dielectric Constant characteristics, given by Figure 6 It can also be seen that the dielectric constant gradually increases from zero in a certain frequency band (11.7GHz to 13.3GHz), and it can be seen from the dotted line that the imaginary part of the corresponding dielectric constant is close to zero ...

Embodiment 2

[0034] The difference from Embodiment 1 lies in the size of the first artificial microstructure 3, and the artificial microstructure 3 after the size increase is as follows: Figure 7 As shown, a1=3.6 mm, a2=3.2 mm, a3=2.8 mm, a4=3.8 mm, a5=0.1 mm, the artificial microstructure 4 is as Figure 4 As shown, c1=c2=2.89 mm, c3=0.184 mm, c4=0.75 mm, such as image 3 For the substrate unit shown, d1=4 mm, d2=8 mm, the simulation diagram obtained by using the above parameters is as follows Figure 8 shown by Figure 8The solid line in the figure shows that the dielectric constant characteristic of the material has the characteristics of multi-resonance, and the dielectric constant is constant in the frequency band (1GHz-7GHz) and is 20. It can be seen that the material has a broadband high dielectric constant The dielectric constant gradually increases from zero in a certain frequency band (11.7GHz to 15GHz), and it can be seen from the dotted line that the imaginary part of the co...

Abstract

The invention relates to a novel metamaterial which comprises at least one material plate layer. Each material plate layer comprises a substrate and artificial microstructures attached onto the substrate. The substrate is virtually divided into a plurality of substrate units arranged in array mode. A pair of artificial microstructures is attached onto each substrate unit. Each pair of artificial microstructures comprises a first artificial microstructure and a second artificial microstructure attached onto each substrate unit. The first artificial microstructures and the second artificial microstructures are of snowflake-shaped structures or of derived structures of the snowflake-shaped structures. Each snowflake-shaped structure comprises two I-shaped structures orthogonal with each other. Each I-shaped structure comprises a first metal line, a second metal line and a third metal line connecting the first metal line and the second metal line, wherein the first metal line and the second metal line are parallel to each other. The third metal lines of the two I-shaped structures intersect and are perpendicular to each other. The material has broadband high dielectric constant in a certain frequency band, has distribution of dielectric constants gradually increasing from zero in another frequency band and can meet requirements of a specific situation.

Description

technical field [0001] The present invention relates to a material, and more particularly, to a new type of metamaterial. Background technique [0002] Metamaterials, also known as artificial electromagnetic materials, are a new type of artificial synthetic materials, which are composed of a substrate made of non-metallic materials and multiple artificial microstructures attached to the surface of the substrate or embedded in the interior of the substrate. The substrate can be virtually divided into multiple substrate units arranged in a rectangular array. Each substrate unit is attached with artificial microstructures to form a metamaterial unit. The entire metamaterial is composed of many such metamaterial units, just like Crystals are composed of countless crystal lattices arranged in a certain way. The artificial microstructures on each metamaterial unit may or may not be identical. Artificial microstructures are planar or three-dimensional structures with certain geom...
