A transmission reflection selective ultranarrow-band metamaterial filter based on electromagnetically induced transparency (EIT) operating at visible wavelengths is demonstrated theoretically and experimentally. The theoretical work starts with the design of an EIT structure with two separate resonance parts. Then the two resonance parts are connected and the hardness of the metamaterial filter is further increased by adding a glass substrate. Numerical simulation results show that the metamaterial filter not only exhibits ultranarrow-band transmission reflection selective spectra, but also exhibits wavelength tunable spectra for both transmission and reflection. To verify the simulation results, a filter sample is fabricated and the spectral responses are measured.

基于电磁感应透明结构的透射反射选择性超窄带超材料滤波器

理论和实验证明了一种基于电磁感应透明 (EIT) 在可见光波长下工作的透射反射选择性超窄带超材料滤波器。理论工作从设计具有两个独立谐振部件的 EIT 结构开始。然后将两个共振部分连接起来,通过增加玻璃基板进一步增加超材料滤波器的硬度。数值模拟结果表明,超材料滤波器不仅表现出超窄带透射反射选择性光谱,而且表现出透射和反射的波长可调光谱。为了验证模拟结果,制作了一个滤波器样品并测量了光谱响应。
