We investigated the influence of periodicity, misalignment, and disorder on the magnetic resonance gap of split-ring resonators (SRRs) which are essential components of left handed-metamaterials (LHMs). The resonance of a single SRR which is induced by the split is experimentally demonstrated by comparing transmission spectra of SRR and closed ring resonator. Misaligning the SRR boards do not affect the magnetic resonance gap, while destroying the periodicity results in a narrower band gap. The disorder in SRR layers cause narrower left-handed pass band and decrease the transmission level of composite metamaterials (CMMs), which may significantly affect the performance of these LHMs.
我们研究了周期性、失准和无序对裂环谐振器（SRR）磁共振间隙的影响，裂环谐振器是左手超材料（LHM）的基本组成部分。通过比较SRR和闭环谐振器的透射光谱，实验证明了由裂环引起的单个SRR的谐振。使SRR板失准不会影响磁共振间隙，而破坏周期性会导致带隙变窄。SRR层中的无序会导致左手通带变窄，并降低复合超材料（CMM）的传输水平，这可能会显著影响这些左手超材料的性能。
