An interdigitated split-ring resonator is proposed and obtains negative permittivity (Îμr), magnetic permeability (Îr), and negative refractive index (n) over a narrow frequency band. This article demonstrates that the proposed structure has a linear frequency response the geometry of the structure and small planar resonators for low frequency metamaterials are possible. The experimental results show that the resonators exhibit a negative refractive index at frequencies of a few hundred MHz to a few GHz.
