Abstract

We report on our numerical work concerning a planar metamaterial exhibiting classical electromagnetically induced transparency (EIT). Using a structure with two asymmetric short strips, we demonstrate that an EIT-like resonance with a high quality factor can be achieved and this high quality factor leads to a large group index of the order of 700. The operation of metamaterial at low temperatures is anticipated to be a promising path towards low-loss metamaterials since nonradiative losses are strongly suppressed. By decreasing temperature from 300 K to 100 K, a controlled behavior with a 26% increase in the quality factor of the resonance and an 85% increase in the group index was observed.

Current and magnetic field distributions in the strips at frequencies corresponding to the points A, B, and C in Fig. 2. The distributions are depicted for a symmetric structure at its absorption frequency 17.8 GHz (a), and for an antisymmetric structure at the transparency frequency 17.8 GHz (b), and absorption frequencies 17.2 GHz (c) and 21 GHz (d).
