Journal ArticleDOI
Nanoengineering of optical resonances
TL;DR: In this paper, a general approach to the making of metal nanoshell composite nanoparticles based on molecular self-assembly and colloid reduction chemistry is described, which can be used to construct a new, composite nanoparticle whose optical resonance can be designed in a controlled manner.
PatentDOI
Active terahertz metamaterial devices
TL;DR: An active metamaterial device capable of efficient real-time control and manipulation of terahertz radiation is demonstrated, which enables modulation of THz transmission by 50 per cent, an order of magnitude improvement over existing devices.
Journal ArticleDOI
A metamaterial absorber for the terahertz regime: Design, fabrication and characterization
Hu Tao,Nathan Ingle Landy,Christopher M. Bingham,Xin Zhang,Richard D. Averitt,Willie J. Padilla +5 more
TL;DR: A metamaterial that acts as a strongly resonant absorber at terahertz frequencies using a bilayer unit cell which allows for maximization of the absorption through independent tuning of the electrical permittivity and magnetic permeability is presented.
Journal ArticleDOI
Terahertz-field-induced insulator-to-metal transition in vanadium dioxide metamaterial
Mengkun Liu,Harold Y. Hwang,Hu Tao,Andrew C. Strikwerda,Kebin Fan,George R. Keiser,Aaron Sternbach,Kevin G. West,Salinporn Kittiwatanakul,Jiwei Lu,Stuart A. Wolf,Fiorenzo G. Omenetto,Xin Zhang,Keith A. Nelson,Richard D. Averitt +14 more
TL;DR: The observation of an insulator–metal transition in vanadium dioxide induced by a terahertz electric field is reported, demonstrating that integration of metamaterials with complex matter is a viable pathway to realize functional nonlinear electromagnetic composites.
Journal ArticleDOI
A metamaterial solid-state terahertz phase modulator
Hou-Tong Chen,Willie J. Padilla,Michael J. Cich,Abul Kalam Azad,Richard D. Averitt,Antoinette J. Taylor +5 more
TL;DR: In this article, a single layer of electrically controlled metamaterial was used to achieve active control of the phase of terahertz waves and demonstrated high-speed broadband modulation.
