Tutorial: An introduction to terahertz time domain spectroscopy (THz-TDS)

Journal of Applied Physics, 2018
Terahertz time-domain spectroscopy (THz-TDS) is a powerful technique for material’s characterization and process control. It has been used for contact-free conductivity measurements of metals, semiconductors, 2D materials, and superconductors ...

Determination of Pesticides in Flour by Terahertz Time-Domain Spectroscopy (THz-TDS) with Voigt Function Fitting and Partial Least Squares (PLS) Analysis

, 2020
Terahertz time-domain spectroscopy (THz-TDS) has been used to analyze mixtures of imidacloprid, carbendazim, and flour substrate. A multiple spectra baseline correction (MSBC) method was adopted to eliminate the oblique baseline and improve the signal-to-
