Electromagnetically induced transparency in terahertz plasmonic metamaterials via dual excitation pathways of the dark mode
(AIP Publishing, 2012-03-26)
We observe the excitation and tuning of electromagnetically induced transparency (EIT) by the interference between different excitation pathways of the dark mode in a planar terahertz metamaterial. The EIT unit cell consists ...
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 ...
Modulating the fundamental inductive-capacitive resonance in asymmetric double-split ring terahertz metamaterials
(AIP Publishing, 2011-03-24)
We investigate resonant transmission of planar asymmetric metamaterials made from double split-ring resonators. As the symmetry of the unit cell resonator is broken by displacing the two gaps away from the center in opposite ...
