In this Letter, a dual-band superconducting metamaterial structure with improved performance based on the proposed multimode split ring resonator (SRR) is proposed, which is constructed by two dual-mode SRRs and a high-impedance transmission line component. Also, its properties and equivalent circuit models are investigated by even-and odd-mode analysis. The mechanism producing four transmission zeros is discussed. To verify this design methodology, the dual-band superconducting metamaterial structure is designed and fabricated with a compact size of 10.6 mm x 13.75 mm. The insertion losses at each passband are 0.1 dB and 0.09 dB, respectively. inally, measured results have a good agreement with simulations.
