Strong influence of packing density in terahertz metamaterials
(AIP Publishing, 2010-12-16)
We investigate the response of a terahertz metamaterial depending on the unit cell density. The fundamental inductive capacitive (LC) resonance has its highest quality (Q) factor for a critical period Pc=lambda/n, with ...
Cryogenic temperatures as a path toward high-Q terahertz metamaterials
(AIP Publishing, 2010-02-19)
Optical properties of planar thin film metamaterials were measured at room and liquid nitrogen temperatures using terahertz time-domain spectroscopy. The operation of metamaterials at cryogenic temperatures is anticipated ...
