在这篇综述中，我们描述了基于耦合谐振器的功能超材料的最新进展。我们首先考虑了模拟电磁感应透明(EIT)的耦合谐振器超材料。我们给出了类EIT超材料的电路模型，并引入了一种新的耦合腔，其中耦合由场梯度提供，从而可以通过改变入射角来改变群速度。然后，我们描述了增强非线性共振超材料中二次谐波的原理。介绍了单谐振超材料中倍频效应的光学和微波实验。还描述了一种使用双共振超材料进一步增强倍频的方法。
In this review, we describe recent developments in functional metamaterials based on coupled resonators. We first consider coupled resonator metamaterials that mimic electromagnetically induced transparency (EIT). We present a circuit model for EIT-like metamaterials and introduce a new coupled resonator in which the coupling is provided by a field gradient so that the group velocity can be varied by varying the incident angle. We then describe the principles for enhancing second harmonic generation (SHG) in nonlinear resonant metamaterials. Optical and microwave experiments of SHG in singly resonant metamaterials are presented. A method for further enhancing SHG using a doubly resonant metamaterial is also described.
