Dual-modes electromagnetically induced transparency based on carbon nanotube films terahertz metasurface

A carbon nanotube metamaterial sensor showing slow light properties based on double plasmon-induced transparency

“…At the frequency of transparent Dip 2 , the group delay can reach 22.26 ps. In Table 2, compared with other sensors, 54–58 our sensor possesses the biggest group delay. Therefore, the proposed CNT-based metamaterial can be applied in the slow light field.…”
