Abstract

  In this study, we propose selectively reconfigurable terahertz meta-molecules by controlling the micro-patterned ion-gel gate structures to change the conductance of graphene bridges between adjacent meta-atoms. Moreover, we experimentally verify that the proposed structures can change the resonance frequency of metamaterial from 1.40, 1.10, to 0.74 THz, by changing the metamaterial unit cell from the individual atom to dimeric and tetrameric molecules, respectively.
