Tunable Metamaterials The electromagnetic response of metamaterials gives rise to exciting phenomena such as cloaking, negative refraction, and perfect lensing. Their response, however, tends to depend strongly on resonant effects, thereby limiting the application bandwidth. Driscoll et al. (p. 1518, published online 20 August) combine a split ring resonator array with the phase change material, VO2, to form a metamaterial in which the response can be tuned. The heat-induced phase change of VO2… 
Electrically driven hybrid photonic metamaterials for multifunctional control
The unique light-matter interaction in metamaterials, a type of artificial medium in which the geometrical features of subunits dominate their optical responses, have been utilized to achieve exotic
Microelectromechanically reconfigurable interpixelated metamaterial for independent tuning of multiple resonances at terahertz spectral region
Tunability in metamaterials has added a new dimension to the functionality and application scope for light–matter interaction in the subwavelength regime. Microelectromechanical-systems-based
Metamaterial-based perfect absorbers
Metamaterials are artificially-engineered materials, possessing properties which are not readily observable in materials existing in nature. Since they show very novel properties such as left-handed
Hybrid Resonators and Highly Tunable Terahertz Metamaterials Enabled by Vanadium Dioxide (VO2)
It is shown that an integration of VO2 structures and conventional metallic resonating components can enable a class of highly tunable THz metamaterials, capable of offering ultrafast modulation of THz radiation.
Realization of variable three-dimensional terahertz metamaterial tubes for passive resonance tunability.
A novel three-dimensional metamaterials tube is investigated to achieve passive resonance tunability and shows a blue-shift which provides a new approach to achieve fl exible resonance Tunability into higher terahertz frequency.
Direct-tuning methods for semiconductor metamaterials
A direct-tuning method for semiconductor metamaterials can be significantly tuned by controlling free carriers’ distributions in unit cells under an applied voltage and opens the path to applications in ultrathin, linearly-tunable, and on-chip integrated optical components.
Photoexcited broadband blueshift tunable perfect terahertz metamaterial absorber
Abstract We present an demonstration of optically tunable metamaterial absorber at terahertz frequencies. The metamaterials are based on two split ring resonators (SSRs) that can be tuned by
