Many scientists and engineers are entering the field and this volume offers a comprehensive and integrated treatment of all aspects of terahertz technology. The three authors, who have been active researchers in this region over a number of years, have designed Terahertz Techniques to be both a general introduction to the subject and a definitive reference resource for all those involved in this exciting research area.




Terahertz Spectroscopy


Book Description

The terahertz regime of the electromagnetic spectrum was largely unexplored due to the lack of technology needed to generate and detect the radiation. However, in the last couple of decades, there has been a dramatic increase in tools needed to harness the radiation. This remarkable progress made in the development of terahertz sources, components, and detectors has resulted in an ever-increasing inquisitiveness of the applications of terahertz technology in a wide range of fields including medicine, pharmaceuticals, security, sensing, and quality assurance. This book, Terahertz Spectroscopy - A Cutting Edge Technology, presents an overview of the recent advances in terahertz technology and their application in a vast array of fields. The scientists and students are encouraged to read and share the content of this volume. The book also provides a good starting point for researchers who are new to the terahertz regime. The various chapters of the book have been written by renowned scientists in different parts of the world who are at the forefront of terahertz research fields. It is our (InTech publisher, editor, and authors) hope that this book will enhance knowledge and stimulate more interest and future research in terahertz technology.

Performing Antiquity


Book Description

Performing Antiquity: Ancient Greek Music and Dance from Paris to Delphi, 1890-1930 investigates collaborations between French and American scholars of Greek antiquity (archaeologists, philologists, classicists, and musicologists), and the performing artists (dancers, composers, choreographers and musicians) who brought their research to life at the birth of Modernism. The book tells the story of performances taking place at academic conferences, the Paris Op ra, ancient amphitheaters in Delphi, and private homes. These musical and dance collaborations are built on reciprocity: the performers gain new insight into their craft while learning new techniques or repertoire and the scholars gain an opportunity to bring theory into experimental practice, that is, they have a chance see/hear/experience what they have studied and imagined. The performers receive the imprimatur of scholarship, the stamp of authenticity, and validation for their creative activities. Drawing from methods and theory from musicology, dance studies, performance studies, queer studies, archaeology, classics and art history the book shows how new scholarly methods and technologies altered the performance, and, ultimately, the reception of music and dance of the past. Acknowledging and critically examining the complex relationships performers and scholars had with the pasts they studied does not undermine their work. Rather, understanding our own limits, biases, dreams, obsessions, desires, loves, and fears enriches the ways we perform the past.
