An addition to the “Optical Science and Engineering” series, the book Terahertz Spectroscopy: Principles and Applications describes methods used for time-domain terahertz spectroscopic measurements, such as the generation and detection of terahertz radiation, the determination of optical constants and the use of femtosecond lasers. The illustrated 360-page resource discusses applications in physics and the materials sciences, including carrier processes in semiconductor materials, and semiconductor nanostructures. It reviews topics in chemistry and biomedicine, including biologically important molecules, pharmaceutical analysis, and the detection of security hazards. Susan L.
