Independent control of near-field-coupled bright and dark resonators for active modulation and frequency tuning of electromagnetically induced transparency analog in terahertz spectral region is experimentally demonstrated. Out-of-plane reconfigurable microcantilever is the active element for resonator control. The proposed metamaterial is miniaturized, electrically controlled, and can achieve up to an order of magnitude change in THz group-delay bandwidth product.
