Research on Reducing the Resonance Frequency of Low Frequency Metamaterials

EasyChair Preprint 11089

Abstract

Metamaterials, as a new type of material for manufacturing electromagnetic and electronic devices, have become the focus of many studies. It can be used in many disciplines, such as chemistry, physics, materials science, optoelectronics, semiconductor science, and equipment manufacturing, and are currently a cutting-edge and strategically significant research topic. Electromagnetic metamaterials are a new type of artificial composite electromagnetic material with controllable dielectric constant and magnetic permeability. This paper establishes a theoretical framework for metamaterials, divides electromagnetic wave media into four quadrants using constitutive parameters, and introduces the calculation method of effective magnetic permeability. This paper is based on a square planar spiral structure. In order to reduce the resonant frequency, a quantitative analysis was conducted on the influence of double-layer mirror structure, patch resistance, and different stacking structures on the resonant frequency. The reference resonant frequency was reduced from 9.6MHz to 7.6MHz, providing a solid foundation for subsequent research.
