Detailed results of the resonance properties of a metamaterial consisting of single split-ring resonators are presented. We employ transmission and reflection spectroscopy at normal incidence. The influence on the resonances of the important parameters characterizing the geometry of the split-ring resonators are analyzed experimentally. In all cases rigorous diffraction theory is employed for comparing the results with theoretical predictions. It is shown explicitly that the resonances depend solely on the design of the unit cells whose sizes are generally scalable. Besides the magnetic resonance associated with the permeability in such a metamaterial, we likewise focus on its plasmonic resonance. We demonstrate that these permittivity resonances are mostly governed by the baseline wires of the split-ring resonators.
