Using a planar metamaterial, which consists of two silver strips, we theoretically demonstrate the plasmonic electromagnetically-induced transparency (EIT)-like spectral response at optical frequencies. The two silver strips serve as the bright modes, and are excited strongly by the incident wave. Based on the weak hybridization between the two bright modes, a highly-dispersive plasmonic EIT-like spectral response appears in our scheme. Moreover, the group index is higher than that of another scheme which utilizes the strong coupling between the bright and dark modes.
通过使用由两条银带组成的平面超材料，我们从理论上证明了在光频率下类似表面等离子体激元电磁诱导透明（EIT）的光谱响应。这两条银带充当亮模式，并被入射波强烈激发。基于这两个亮模式之间的弱杂化，在我们的方案中出现了高度色散的类似表面等离子体激元EIT的光谱响应。此外，群折射率高于另一种利用亮模式和暗模式之间强耦合的方案。
