About the book
Terahertz Technology reviews the developments of 0.1–3 terahertz (THz) electromagnetic (EM) waves in novel radiation–detection, fundamentals of THz optics, and the applications. The detection and radiation of THz EM waves are normally available from commercial instruments based on the mature techniques of high-peak-power lasers, semiconductors, and optomechanical fabrication. However, further applications for steering THz waves are still restricted from the methodologies of the THz propagation media, emitters and detectors.
In this book, such THz technology is regarded as state of the art and is presented for the abilities to conquer technical limitations or improve performance in various applications, such as imaging, sensing, and communication systems. THz propagation media are different from those media in the infrared-ray or visible-light spectra because their specifications are designed according to the coherent lengths, photon energy, absorption, and dispersion of THz waves. Optic interference perturbs THz wave power observation in the free space because continuous THz waves have coherent lengths of 0.1–3 mm, approximating the sample thicknesses, aperture sizes, vibration amplitudes, and location deviation of the detector position. The technology of THz optics specifically presents that THz propagation materials are reliable for steering THz EM waves after the readers learn the required methodologies from this text.
