The authors investigate the resonances of split-ring resonator (SRR) structures experimentally and theoretically. The transmission measurements were performed on a single SRR unit cell and periodic arrays of SRRs. The magnetic response of the SRR structure was demonstrated by comparing the SRRs' transmission spectra of with that of closed ring resonators (CRR). The surface currents along the SRR surfaces at the magnetic and electrical resonances were simulated and a circular surface current was observed at the magnetic resonance frequency. The transmission characteristics of SRR arrays with two different orientations were also presented by varying the incident angles of the plane wave.
