Abstract

Artificially constructed materials, including metamaterials with negative magnetic permeability (μ) at megahertz frequencies, have been applied in various fields and the construction of new devices. Among these applications, the split-ring resonators (SRRs) and spiral resonators (SRs) are the most widely used metamaterial cells, especially in telemetry and antenna systems proposed in the past few years. In this paper, one particular cell, whose structure is square spiral wires printed on both sides of a dielectric substrate, is selected as the investigated resonator. Numerous simulations are conducted to study the properties of both magnetic resonance and effective permeability. The effect of the geometrical parameters on the resonance frequency and the impact of the number of turns of spiral resonator on the permeability are investigated. The effective permeability of the periodic SR array varies with the metal width and the gap spacing. The values of  are extracted at a chosen frequency of 29.8 MHz, based on which the geometrical parameters of the SR array whose relative permeability is -1 can be determined. This kind of artificial magnetic materials are able to be used for improving the efficiency of a wireless power transfer system.
