1st Edition
Handbook of Terahertz Technologies Devices and Applications
Terahertz waves, which lie in the frequency range of 0.1–10 THz, have long been investigated in a few limited fields, such as astronomy, because of a lack of devices for their generation and detection. Several technical breakthroughs made over the last couple of decades now allow us to radiate and detect terahertz waves more easily, which has triggered the search for new uses of terahertz waves in many fields, such as bioscience, security, and information and communications technology.
The book covers some of the technical breakthroughs in terms of device technologies. It discusses not only the theoretical details and typical features of the technology described, but also some issues and challenges related to it. In addition, it is shown what can actually be done with the terahertz-wave technologies by introducing several successful demonstrations, such as wireless communications, industrial uses, remote sensing, chemical analysis, and 2D/3D imaging.

His research interests include millimeter wave and terahertz photonics and their application to sensors and wireless communications.
"This book covers the state-of-the-art of a broad range of relevant THz technologies in concise chapters. ... The handbook is a practical and relevant guide to current THz device technologies. Terahertz wave science is a rapidly evolving field of research and emerging applications. The book accounts for this trend by covering recent, important technical breakthroughs in THz device technologies. The concepts are clearly described using text, illustrations, and exemplary results rather than complex mathematical equations. ... The book is useful for professional scientists or engineers who are interested in understanding the concepts of modern THz device technologies. The difficulty level of the presentation makes the book an appropriate text for graduate students entering the field of THz technology research. For chemists, biologists, and professionals in the medical and pharmaceutical sciences, the book provides a good first introduction to the capabilities of modern THz technologies in chemical spectroscopy, sensing, and imaging. ... The book’s publication is timely. The interest in employing modern THz technologies for research in analytical chemistry, biology, and materials science is growing. Also, more and more of the THz technologies discussed in the book are becoming available as commercial products. This book is a good reference for scientists and engineers who want to make an informed decision about adapting modern THz technologies for their research."
—Ingrid Wilke, Department of Physics, Applied Physics, and Astronomy, Rensselaer Polytechnic Institute, Troy, New York, USA, from Analytical and Bioanalytical Chemistry, November 2015"This is an extremely welcome addition to the growing number of books addressing the terahertz (THz) frequency region of the spectrum, which has been the subject of spectacular international growth over the last 20 years. The editors have brought together a series of articles covering an exceptionally broad range of topics, from fundamental principles through to applications. This comprehensive book makes not only an excellent introduction for researchers starting out, but also a very useful reference for those with experience in the field already."
—Prof. Giles Davies, University of Leeds, UK"THz technologies are expected to deliver lots of potentialities for applications in various fields such as spectroscopy, imaging, security, and communications. This book covers a wide range of technical breakthroughs in the THz field showing what we can do with THz waves. Authored by an impressive selection of experts, this is a great reference source for everyone following this promising technology."
—Prof. Kodo Kawase, Nagoya University, Japan"A truly wonderful and comprehensive overview of THz devices and techniques targeted, amongst many other applications, at the most likely mainstream commercial use for THz systems: wireless communications."
—Dr. Peter Siegel, California Institute of Technology, USA
