Coupled mode resonators provide an access route for the realization of electromagnetically induced transparency (EIT) analogues in the terahertz spectral region. On page 541, C. Lee and co-workers experimentally realize a microelectromechanical system (MEMS)-based metamaterial to provide both active modulation of EIT intensity and spectral tuning of the EIT peak. This is achieved through selective reconfiguration of bright and dark mode resonators, respectively. An order of magnitude change in delay-bandwidth product is achieved.
