我们提出了一种具有电磁感应透明度的超材料的平面设计，该设计可以在微波频段进行实验验证。该设计基于劈裂环谐振器与同一平面上的断线的耦合。我们研究了传输窗口参数对耦合强度和单个谐振器电路元件的敏感性，并用两个线性耦合的洛伦兹谐振器来解释结果。我们的超材料设计将低损耗与传输窗口中谐振响应相关的极小群速度相结合，使其适用于室温下的慢光应用。(C) 2009年美国光学学会
We present a planar design of a metamaterial exhibiting electromagnetically induced transparency that is amenable to experimental verification in the microwave frequency band. The design is based on the coupling of a split-ring resonator with a cut-wire in the same plane. We investigate the sensitivity of the parameters of the transmission window on the coupling strength and on the circuit elements of the individual resonators, and we interpret the results in terms of two linearly coupled Lorentzian resonators. Our metamaterial designs combine low losses with the extremely small group velocity associated with the resonant response in the transmission window, rendering them suitable for slow light applications at room temperature.
