Time-Domain Terahertz Spectroscopy and Sensing

2001
Spectroscopy in the terahertz (THz) region of the electromagnetic spectrum is an important and growing field of research with a broad range of applications. The characteristic properties of THz radiation (1 THz = 1012 Hz), localised between the infrared and the microwave frequencies, suggest many applications in the spectroscopy of gases, liquids and ...

Terahertz Time-Domain Spectroscopy of Imidazolium Ionic Liquids

The Journal of Physical Chemistry B, 2007
We have measured the terahertz (THz) complex dielectric spectra of imidazolium ionic liquids by THz time-domain spectroscopy (THz-TDS) in the frequency range from 5 (0.15 THz) to 140 cm(-1) (4.2 THz). The ionic liquids investigated are 1-ethyl-3-methylimidazolium (EMIm+)/trifluoromethanesulfonate (TfO-), EMIm+/tetrafluoroborate (BF(4)-), 1-butyl-3 ...

Terahertz Time-Domain Spectroscopy of Selected Layered Silicates

Clays and Clay Minerals, 2009
AbstractMicaceous layer silicate clay minerals are attractive materials for applications involving non-linear optics because of their low cost and ability to form well ordered, platy aggregates, but such applications require precise knowledge of the dielectric behavior of the clay.

Terahertz Time-Domain Spectroscopy for Studying Absorbable Hemostats

IEEE Transactions on Terahertz Science and Technology, 2016
This study deals with the kinetics of absorbable hemostats used for supporting the hemostasis and wound closure during surgical intervention. There are several types of hemostats of different composition therefore with different mechanism of action.

Measurement of nanocomposite scintillators by terahertz time domain spectroscopy

Applied Optics
Nanocomposite scintillators are expected to combine the advantages of inorganic and plastic scintillators, such as high detection efficiency, high light yield, fast decay time, low cost, and ease of processing. They are currently the forefront and hot field of scintillator research.

Terahertz Time-Domain Spectroscopy of Glasses

2019
Terahertz-time domain spectroscopy () uses the real and imaginary parts of the dielectric and optical constants for glass characterization over a wide frequency range in the electromagnetic spectrum. This chapter provides an overview and analysis of various THz spectrometers and typical data sets over \(0.1{-}10\,{\mathrm{THz}}\).

Time-Domain and Ultrafast Terahertz Spectroscopy

2016
Many basic condensed matter properties and phenomena are governed by the spectrum of electronic and vibrational degrees of freedom at low energies, comparable to the Boltzmann thermal energy (kBT). They determine both the material’s ground state at finite temperature and its dynamical response to electromagnetic or electronic perturbations.
