Four types of split ring resonators (SRRs), the so-called single-slitSRRs, two-slitSRRs (TSRRs), double-ring SRRs, and modified SRRs,have been considered and numerically investigated for the comparative analysis in connection with their suitability to the design of tunable metamaterials. It is found that the TSSR configuration on the gigahertz resonance reveals a larger variationin the magnetic resonance frequency throughthe influences of the SRR size scaling, the slit width and the substrate permittivity.Based on the TSRRstructure infiltrated with liquid crystals (LCs) in the sandwich substrate, a tunablemagnetic metamaterial was proposed in this study.The main relevant contribution of this paper is to provide a tuning procedure via controlling the director orientation of anisotropic LCs and to show that the TSRR structure can be designed to exhibit negative permeability over a broad frequency interval. The magnetic resonance frequencies could be adjusted in the microwave range of about 7.82 to 8.92 GHz.
