Terahertz superconducting plasmonic hole array
Zhen Tian, Ranjan Singh, Jiaguang Han +3
We demonstrate thermally tunable superconductor hole array with active control over their resonant transmission induced by surface plasmon polaritons . The array was lithographical…
Superconductor terahertz metamaterial
Jianqiang Gu, Ranjan Singh, Zhen Tian +4
We characterize the behaviour of split ring resonators made up of high-transition temperature YBCO superconductor using terahertz time domain spectroscopy. The superconductor metam…
Cryogenic temperatures as a path towards high-Q terahertz metamaterials
Ranjan Singh, Zhen Tian, Jiaguang Han +3
Optical properties of planar thin film metamaterials were measured at room and liquid nitrogen temperatures using terahertz time-domain spectroscopy. The operation of metamaterials…
Random terahertz metamaterials
Ranjan Singh, Xinchao Lu, Jianqiang Gu +2
Using terahertz time domain spectroscopy we investigate the normal incidence transmission through periodically and randomly arranged planar split ring resonators (SRRs). Introducti…
