Embodiment Construction

[0035] The invention provides a novel metamaterial. Compared with the existing metamaterial, the dielectric constant of the metamaterial is improved by changing the topological shape of the artificial microstructure.

[0036] Such as image 3 As shown, the metamaterial includes at least one substrate 1 with uniform and equal thickness. If there are multiple substrates 1, the substrates 1 are stacked in sequence along the direction (z-axis direction) perpendicular to the substrate plane, and are assembled or placed between every two substrates 1. The gap is filled with a substance that can connect the two, such as a liquid substrate material, which will bond the two existing substrates 1 after curing, so that multiple substrates 1 form a whole. The substrate 1 can be made of high dielectric constant ceramic materials such as FR-4, F4b, CEM1, CEM3 or TP-1.

[0037] Each substrate 1 is virtually divided into a plurality of identical cubic substrate units next to each other, and ...

Abstract

The invention relates to a metamaterial with a high dielectric constant, which comprises a substrate and an artificial micro structure attached on the substrate, wherein the artificial micro structure comprises a first metal wire and a second metal wire which are mutually parallel, and also comprises a third metal wire one end of which is a free end and the other end of which is connected with the first metal wire, and a fourth metal wire one end of which is a free end and the other end of which is connected with the second metal wire, and the third metal wire and the fourth metal wire are wound around in parallel in the same direction to form two independent helical wires which are not intersected. The dielectric constant of the metamaterial with the artificial micro structure is greatlyincreased, thus the metamaterial with the high dielectric constant can be widely applied to fields such as antenna manufacture, semiconductor manufacture, and the like; meanwhile, the technical scheme breaks through the defect of limited dielectric constant in unit volume in the prior art, and generates an immeasurable function to miniaturization of a microwave device.

Description

technical field [0001] The invention relates to the field of metamaterials, more specifically, to a metamaterial with high dielectric constant. Background technique [0002] The dielectric constant is a parameter of the response of the material to the electric field. When the material is applied with an electric field, it will generate induced charges and weaken the electric field. The ratio of the applied electric field in the original vacuum to the electric field in the final material is the dielectric constant. [0003] In nature, any material has its specific dielectric constant value or dielectric constant curve under certain conditions. When a material with a higher dielectric constant is placed in an electric field, the strength of the field will drop considerably within the dielectric material. Materials with high dielectric constants, such as dielectric insulators, are often used to make capacitors. Moreover, in high dielectric constant materials, the wavelength o...
