In these modern times, the growing applications in communication, sensing, security, safety, spectroscopy, manufacturing, bio-medical, agriculture, imaging, etc. demand for higher resolution, greater speeds, and wider bandwidth support. Thanks to THz technology that makes it possible due to its enormous advantages like non-ionizing signal nature, compactness, higher resolution, spatial directivity, high-speed commu-nication, and greater bandwidth. Since the THz radiation covers frequencies from 0.1THz to around 10THz and is highly attenuated by atmospheric gases, it is mainly used in short-distance applications.

This book is aimed to bring the emerging application aspects of THz technology and various modules used for its successful realization. It gathers scientific tech-nological novelties and advancements already developed or under development in the academic and research communities. This work focuses on recent advances, different research issues in terahertz technology and would also seek out theoretical, methodological, well-established, and validated empirical work dealing with these different topics. The book chapters cover a very vast audience from basic science to engineering, technology experts, and learners. This could eventually work as a text-book for engineering and communication technology students or science master’s programs and for researchers as well. The chapters of this book also serve the common public interest by presenting new methods for application areas of technology, its working, and its effect on the environment and human health, etc.

In particular, this textbook covers design considerations and current trends of THz antennas and antenna arrays to deal with the transmission and reception of THz EM waves. It also presents a discussion on metamaterial structures, meta-surfaces, and absorbers to be used for some kind of sensing and detection applications. Further-more, it reports on THz wireless communication aspects, 6G network issues and challenges, advantages, and disadvantages, generation and detection of THz waves, Signal and Communication Processing for THz communication, reconfigurable low-noise amplifier (LNA) design, III-Nitride HEMTs for THz Applications, photonic crystal fiber for sensing applications, THz Design Variable Estimation by Deep Optimization, and THz Imaging issues.
