Abstract

In this paper, we numerically and experimentally demonstrate classical analogy of electromagnetically induced transparency (EIT) with simultaneously exciting the electric and the magnetic resonance. The cut wire and the split-ring resonator (SRR) are chosen as the bright and the quasi-dark EIT resonators, respectively. Under incident electromagnetic wave illumination, an EIT-like sharp transmission window can be observed. The group index exceeds 140, which can be applied for slow electromagnetic wave velocity. Furthermore, the underlying physics can be interpreted by the concept of hybridization model. The simultaneous excitation of the electric and the magnetic resonance can make up for the shortcomings of the other existing designs. More importantly, it can enrich metamaterial analogy of electromagnetically induced transparency.
