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 ...
Dielectric response of soft mode in ferroelectric SrTiO3
(AIP Publishing, 2007-01-16)
The authors report far-infrared dielectric properties of powder form ferroelectric SrTiO3. Terahertz time-domain spectroscopy (TDS) measurement reveals that the low-frequency dielectric response of SrTiO3 is a consequence ...
