Terahertz superconductor metamaterial

Applied Physics Letters, 2010
We characterize the behavior of split ring resonators made up of high transition temperature yttrium barium copper oxide superconductor using terahertz time-domain spectroscopy measurements and numerical simulations. The superconductor metamaterial is found to show a remarkable change in the transmission spectra at the fundamental inductive-capacitive ...

Active Control and Large Group Delay in Graphene-Based Terahertz Metamaterials

Journal of Physical Chemistry C, 2019
A distinct plasmon-induced transparency (PIT) window has been realized in our novel design of |+|-shaped graphene metamaterials, which consist of two identical graphene strips and a cross-shaped graphene resonator in the right middle.

Optically tuneable broadband terahertz metamaterials using photosensitive semiconductor material

Journal of Modern Optics, 2018
We present optically tuneable broadband terahertz metamaterials consisting of photosensitive semiconductor material. The characteristics of semiconductor materials are very important for terahertz functional devices, which is strongly dependent on the ...

Terahertz Metamaterials and Metadevices

2017
Terahertz metamaterials are designed to interact at terahertz (THz) frequencies, which is usually defined as 0.1–10 THz. Terahertz regime is located at the interface of electronics and photonics where technologies directly translated from microwave and optical regime generally fail to operate.
