Optical tuning and ultrafast dynamics of high-temperature superconducting terahertz metamaterials
Ranjan Singh, Jie Xiong, Abul K. Azad +5
Through the integration of semiconductors or complex oxides into metal resonators, tunable metamaterials have been achieved by a change of environment using an external stimulus. M…
Application of metasurface description for multilayered metamaterials and an alternative theory for metamaterial perfect absorber
Jiangfeng Zhou, Hou-Tong Chen, Thomas Koschny +4
We analyze single and multilayered metamaterials by modeling each layer as a metasurface with effective surface electric and magnetic susceptibility derived through a thin film app…
Thermal tunability in terahertz metamaterials fabricated on strontium titanate single crystal substrates
Ranjan Singh, Abul K. Azad, Q. X. Jia +2
We report an experimental demonstration of thermal tuning of resonance frequency in a planar terahertz metamaterial consisting of a gold split-ring resonator array fabricated on a…
