We report a novel type of electromagnetically induced transparency (EIT) analogue based on metamaterials (MMs) with hybrid structures, in which spiral and cut-wire structures serve as bright-mode resonators with the spoof electric localized surface plasmons and electric dipole resonance. With the simulations and experiments, the EIT analogue generated by the frequency detuning and hybridization between the resonators is verified. The simulated surface charge density and electric and magnetic field distributions, together with the theoretical analysis based on the Lorentz oscillator model, reveal the principle of the EIT analogue. Moreover, the transmission window of the MM demonstrates linear dependence on the refractive index’s change of surrounding media, showing the potential as a tool for environmental detection.

基于欺骗性电局部表面等离激元和电偶极子之间的亮-亮模式耦合的电磁感应透明度模拟

我们报告了一种新型的基于超材料的具有混合结构的电磁感应透明（EIT）类似物，其中螺旋和切割线结构充当了具有局部电气局部等离子体激元和电偶极子共振的亮模谐振器。通过仿真和实验，验证了谐振器之间的频率失谐和混合产生的EIT模拟。模拟的表面电荷密度，电场和磁场分布，以及基于洛伦兹振荡器模型的理论分析，揭示了EIT模拟的原理。此外，MM的透射窗口显示出对周围介质折射率变化的线性依赖性，显示了作为环境检测工具的潜力。
