Highly tunable optical activity in planar achiral terahertz metamaterials
Ranjan Singh, Eric Plum, Weili Zhang +1
Using terahertz time domain spectroscopy we demonstrate tunable polarization rotation and circular dichroism in intrinsically nonchiral planar terahertz metamaterials without twofo…

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…
