We theoretically demonstrate the possibility of dynamically controlling the response of metamaterials at optical
frequencies using the well known phenomenon of coherent control. Our results predict a variety of effects ranging from
dramatic reduction of losses associated with the resonant response of metamaterials to switchable ultraslow to
superluminal propagation of pulses governed by the magnetic field of the incident wave. These effects, generic to all
metamaterials having a resonant response, involve embedding the metamaterial in resonant dispersive coherent
atomic/molecular media. These effects may be utilized for narrow band switching applications and detectors for radiation
below predetermined cut-off frequencies.
