Broadband circular polarization time-domain terahertz spectroscopy [PDF]

Physical Review Materials, 2020
Light-matter interactions are key in providing fundamental information about materials. Even in the linear-response regime, the spectroscopic response of a material encodes in it many properties of the ground state as well as of its excitations.

Terahertz Time-Domain Spectroscopy

Abstract This chapter briefly reviews the technique of terahertz time-domain spectroscopy (THz-TDS), a powerful method for accessing the spectral range from 100 GHz up to several THz. We first discuss the physical principles upon which the method relies.

Terahertz time-domain spectroscopy of chondroitin sulfate

Biomedical Optics Express, 2018
Chondroitin sulfate (CS), derived from cartilage tissues, is an important type of biomacromolecule. In this paper, the terahertz time-domain spectroscopy (THz-TDS) was investigated as a potential method for content detection of CS. With the increase of the CS content, the THz absorption coefficients of the CS/polyethylene mixed samples linearly ...
