An interdigitated split‐ring resonator is proposed and obtains negative permittivity (ε r ), magnetic permeability (μ r ), 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. © 2010 Wiley Periodicals, Inc.
