摘要: In this paper, we investigate a metamaterial formed by a planar array of a metallic L-shaped structure and a cut wire (CW), which behaves as an analogue of the electromagnetically induced transparency (EIT). The double transmission peaks are formed by the destructive interference of two bright-modes and a quasi-dark mode. The two bright-modes are respectively excited by the L-shaped structure and CW. The unit structure itself performs a quasi-dark mode. The group refractive indexes are over 20 in the first transmission peak, and 117 in the second transmission peak, thus offering potential applications in slow light devices. Finally, all the above characteristics are achieved in just one simple unit cell.
