Terahertz spectroscopy: an introductory textbook (1st)

Terahertz time-domain spectroscopy (THz-TDS) is a unique technique for characterising the response of materials and devices in the far-infrared region of the electromagnetic spectrum.

Based on the measurement of transmitted or reflected ultra-short electromagnetic pulses and on a Fourier-transform of the recorded waveforms, THz-TDS permits fast and precise determination of the permittivity or permeability of materials over a wide bandwidth.

This book is devoted to the determination of this spectral response of samples from the recorded waveforms.

The book presents the basics of THz-TDS, including latest and interesting research on THz domain.

It overviews the main classical far-infrared techniques and describes a variety of THz-TDS setups.
