Problems solved by technology

[0004] With the rapid development of technology, people have higher and higher requirements for the application of materials. In some occasions, the required dielectric constant value is much higher than that of the existing materials in nature. The existing dielectric constant Higher dielectric insulators cannot meet the requirements, which will cause bottlenecks in technology and product development

Abstract

The invention relates to a metamaterial which comprises at least one metamaterial sheet layer, wherein each metamaterial sheet layer comprises a substrate and a metal micro structure attached on the substrate, the metal micro structure comprises a plurality of fan-shaped structures obtained after at least one straight line with a certain width, which passes through the center of a circle, is etched on a solid circular metal sheet. The invention also provides a filter using the metamaterial. The filter comprises a resonant cavity and a harmonic oscillator arranged inside the resonant cavity, wherein the harmonic oscillator is made of the metamaterial. The dielectric constant of the metamaterial with the metal micro structure is greatly enhanced, and the metamaterial is applied to the filter so that the miniaturization of the filter is facilitated.

Description

technical field [0001] The invention relates to the field of new materials, more specifically, an artificial electromagnetic material with high dielectric constant and a filter using the material. 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 electric field will drop considerably within the dielectric material. In high dielectric constant materials, the wavelength of electromagnetic waves is very short, which can greatly ...
