摘要：
We propose a hybrid metamaterial whose unit cell is consisted of a silicon ring and a silver T-shaped antenna. We use finite-difference time-domain to simulate the electromagnetically-induced transparency (EIT)-like effect and slow-light performance of the metamaterial. Then, we also study the influence of different parameters, and finally achieve a group refractive index of 2253 slow-light effect based on an EIT-like effect. Moreover, we use two-dimensional material WS2 to tune the slow-light effect. This tuning method brings forward a research idea for the slow-light tuning of active metamaterials.
