论文摘要
在本文中，提出了一种新结构，该结构有望实现双波段电磁诱导的透明度（EIT）样效应。它可以被视为由双波段U形谐振器组成的光晶状元素的超材料。明亮模式之间的近场耦合会产生类似EIT的效果。优化参数后，我们的数值模拟结果与理论分析非常吻合。 EIT样效果可以显着降低透明窗口附近的组速度，可能会在慢灯传输和光学存储中获得更大的潜在应用。
In this paper, a new structure is proposed which is expected to realize dual-band electromagnetically induced transparency (EIT)-like effect in terahertz spectrum. It can be regarded as a metamaterial of grating-like elements composed of dual-band U-shaped resonators. The near-field coupling between bright modes can produce EIT-like effect. After optimizing the parameters, our numerical simulated results are in good agreement with the theoretical analysis. The EIT-like effect can significantly reduce the group speed near the transparent window, may gain more significant potential applications in slow-light transmission and optical storage.
