摘要

研究了由两个扭裂环谐振器组成的立体SRRs超材料的传感性能。由于系统中存在较强的杂化效应，透射波的偏振态在共振处发生了很大的变化。由于立体srrs结构与周围介质强耦合，透射波的偏振变化对环境介质的折射率变化非常敏感。以极化比PRtran = Ty/Tx作为传感参数，其在杂化磁等离子体共振时的优值可达22.3。结果表明，立体srrs超材料可应用于光学传感器等相关领域。

Magnetic Plasmon Sensing in Twisted Split-Ring Resonators

We studied the sensing properties of stereo-SRRs metamaterials composed from two twisted split-ring resonators (SRRs). Due to the strong hybridization effect in the system, the polarization state of the transmitted wave is greatly changed at resonances. Since the stereo-SRRs structure is strongly coupled to the surrounding medium, the polarization change of the transmitted waves is quite sensitive to the refractive index change of the environment medium. The polarization ratio PRtran = Ty/Tx is used as sensing parameter and its figure of merit can reach 22.3 at the hybridized magnetic plasmon resonance. The results showed that the stereo-SRRs metamaterial can be applied to optical sensors an or other related field.
