dc.description.abstract | Unusual performances of metamaterials such as negative index of refraction, memory effect, and cloaking originate from the resonance features of the metallic composite atom1−6. Indeed, control of metamaterial properties by changing dielectric environments of thin films below the metallic resonators has been demonstrated7−11. However, the dynamic control ranges are still limited to less than a factor of 10,7−11 with the applicable bandwidth defined by the sharp resonance features. Here, we present ultra-broad-band metamaterial thin film with colossal dynamic control range, fulfilling present day research demands. Hybridized with thin VO2 (vanadium dioxide)(12-18) films, nanoresonator supercell arrays designed for one decade of spectral width in terahertz frequency region show an unprecedented extinction ratio of over 10000 when the underlying thin film experiences a phase transition. Our nanoresonator approach realizes the full potential of the thin film technology for long wavelength applications. | - |
