摘要：

In this article, we numerically and experimentally investigate a metamaterial geometry capable of exhibiting dual hand electromagnetic induced transparency (EIT) effect in terahertz frequency regime. The meta-molecule unit consists of two asymmetric C resonators, placed alternately on both sides of a cut-wire (CW). The near field coupling between the CW and C resonators of the MM structure leads to the evolution of the dual-band EIT effect. We observe that the dual-band EIT effect can be modulated by changing the distance between the CW and the 2C resonators. Our study can play an important role in the development of multi-band slow light devices, modulators and also for sensing applications.
