Active control of electromagnetically induced transparency analogue and slow light phenomena via MEMS based terahertz metamaterials

Classical analogue of electromagnetically induced transparency mediated by near field coupling in meta-atom resonators form the basis for design of slow light metamaterial devices. Here, we experimentally demonstrate the active control of individual resonators in the near-field coupled system. This allows for active modulation and spectral tuning of the transparency peak and hence the slow light behavior in terahertz spectral range.
