This new book describes modern terahertz (THz) systems and devices and presents practical techniques for accurate measurement with an emphasis on evaluating uncertainties and identifying sources of error. This is the first THz book on the market to address measurement methodologies and issues -- perfect for practitioners and aspiring practitioners wishing to learn good measurement practice and avoid pitfalls. This book provides a brief review of different THz systems and devices, followed by chapters detailing the measurement issues encountered in using each of the main types of THz systems, and a guide to performing measurements rigorously. Particular attention is given to evaluating uncertainties, and recognizing potential sources of errors. The main focus is on time-domain spectroscopy, by far the most widely used technique. Readers are also presented with examples of applications with the emphasis on utility, both in research and in industry. Terahertz time-domain spectrometers Parameter extraction in time-domain spectrometers Metrology for time-domain spectrometers Evaluation of uncertainty in time-domain spectroscopy Metrology for Fourier transform spectrometers Terahertz spectrometer calibration Terahertz imaging Metrology for vector network analyzers Terahertz optics Terahertz laser sources Electronic sources of terahertz radiation and terahertz detectors.
