Principles of Terahertz Time-Domain Spectroscopy [Hardcover]

Terahertz time-domain spectroscopy (THz-TDS) is a unique technique for characterizing 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.

 

 Introduction.  The THz Frequency Range.  Classical Far-Infrared Spectroscopy Techniques.  THz-TDS Instrumentation.  Extracting the Refractive Index from Transmission TDS Data.  Extracting the Refractive Index from Reflection TDS Data.  Pump-and-Probe THz-TDS.  Waveguides, Metamaterials and Plasmonic Devices.  Characterization of Anisotropic Materials.  THz-TDS of Scattering Samples.  Noise in THz-TDS Systems.  Precision of the THz-TDS Extraction.  Advanced Techniques.

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. It provides a comprehensive overview of the extraction procedures that are used to calculate the permittivity.
