IEEE Transactions on Terahertz Science and Technology, 2020
Terahertz Time-Domain Spectroscopy (THz-TDS) has been a powerful tool for material characterization. The Fabry–Perot (FP) effect caused by the multiple reflections within the sample exists inherently, which makes the echoes contaminated.

Tera Tool [terahertz time-domain spectroscopy]
IEEE Circuits and Devices Magazine, 2002The terahertz differential time-domain spectroscopic method is applied to characterize the dielectric and optical properties of a variety of thin films at terahertz frequency. The results of several samples including silicon dioxide, parylene-n polymer film, tantalum oxide film, and protein thin layer samples were presented.

IEEE Transactions on Terahertz Science and Technology, 2020
Simultaneous measurement of the substrate/film thickness and film conductivity in a thin metal film/substrate structure is still challenging. In this article, we propose a method for the measurement based on a terahertz time-domain spectroscopy system by

Time-Domain Terahertz Spectroscopy and Sensing
2001Spectroscopy 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 ...

On-Chip Terahertz Time-Domain Spectroscopy
2021Terahertz time-domain spectroscopy (THz-TDS) allows the direct measurement of optical and charge carrier properties of materials in a region of the electromagnetic spectrum inaccessible to most other spectroscopic techniques. We have adapted the technique to an on-chip arrangement that allows us to measure these properties in nanoscale materials with ...

Far-infrared terahertz time-domain spectroscopy of flames
Optics Letters, 1995We present what is to our knowledge the first comprehensive far-infrared absorption measurement of flames. These measurements, covering the region of 7-88 wave numbers (0.2-2.65 THz) are only now made possible by the technique of terahertz time-domain spectroscopy. We observe a large number of absorption lines-including those of water, CH, and NH(3)-in

Terahertz Study of Trichloroanisole by Time-Domain Spectroscopy
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007This work presents THz time-domain spectroscopy applied in transmission to three TCA compounds (2,3,4-TCA, 2,4,6-TCA and 2,5,6-TCA) in pellet form pressed with polyethylene. Experiment results would be compared to theoretical modeling of the vibrational modes.

Terahertz Time-Domain Spectroscopy of Imidazolium Ionic Liquids
The Journal of Physical Chemistry B, 2007We 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 ...
