Terahertz (THz) radiation, which is electromagnetic radiation in a frequency int- val from 0.3 to 10 THz (1 mm–30 ?m wavelength), is the next frontier in science and technology. This band occupies a large portion of the electromagnetic sp- trum between the infrared and microwave bands. Basic research, new initiatives, and developments in advanced sensing and imaging technology with regard to the THz band remain unexplored compared to the relatively well-developed science and technology in the microwave and optical frequencies. Historically, THz technologies were used mainly within the astronomy c- munity for studying the background of cosmic far-infrared radiation, and by the laser-fusion community for the diagnostics of plasmas. Since the ?rst demonstration of THz wave time-domain spectroscopy in the late 1980s, there has been a series of signi?cant advances (particularly in recent years) as more intense THz sources and higher sensitivity detectors provide new opportunities for understanding the basic science in the THz frequency range.
Microwave photonics is an important interdisciplinary field that, amongst a host of other benefits, enables engineers to implement new functions in microwave systems. With contributions from leading experts, Microwave Photonics: Devices and Applications explores this rapidly developing discipline. It bridges a gap between microwave and photonic engineering, providing an accessible interpretation of the current available research material and a detailed introduction to various aspects of the area. Opening with an overview to the subject, this book covers direct modulation, photonic oscillators for THz signal generation, and terahertz sources. It takes a unique application- focused approach and describes: analogue fibre-optic links; fibre radio technology; microwave photonic signal processing; measurement of microwave photonic components, and; biomedical applications. This text is ideal for practising microwave and fibre optics communication engineers wishing to improve their knowledge, and for researchers and graduate students wanting an overview of the subject.
The inherent advantages and potential payoffs of the terahertz (THz) regime for military and security applications serve as an important driver for interest in new THz-related science and technology. In particular, the very rapid growth in more recent years is arguably most closely linked to the potential payoffs of THz sensing and imaging (THz-S&I).This book presents some of the leading fundamental research efforts towards the realization of practical THz-S&I capabilities for military and security applications. Relevant subjects include theoretical prediction and/or measurement of THz spectroscopic phenomenon in solid-state materials such as high explosives (e.g. HMX, PETN, RDX, TNT, etc.),...
This book brings together seven selected best papers presented at the 2014 Russia-Japan-USA Symposium on Fundamental and Applied Problems of Terahertz Devices and Technologies (RJUS TeraTech-2014), which was held at the University of Buffalo, New York, USA on 17-21 June 2014.As the third in the series of annual meetings, RJUS TeraTech-2014 continues to be an excellent platform for researchers to exchange their recent original results, and to deal with the technical challenges and barriers of transitioning the research results into the THz system-level applications. The symposium focuses on 2 main areas, namely, interaction of THz radiation with micro- and nano-structures, and advanced solid-state THz emitters and sensors. Leading experts from academia, industry, and government agencies from three countries, including USA, Japan, and Russia, contributed to the collection of research results and developments.This book, covering issues ranging from basic Thz-related phenomena to applications in sensing, imaging, and communications, contains some ground-breaking works in the industry, and will be a useful reference for device and electronics engineers and scientists.
Designed for independent learning, this is the first book for advanced undergraduate and graduate students in this exciting field.
At last here is the long-awaited, first Western-language reference guide focusing exclusively on Chinese literature from ca. 700 B.C.E. to the early seventh century C.E. Alphabetically organized, it contains no less than 1095 entries on major and minor writers, literary forms and "schools," and important Chinese literary terms. In addition to providing authoritative information about each subject, the compilers have taken meticulous care to include detailed, up-to-date bibliographies and source information. The reader will find it a treasure-trove of historical accounts, especially when browsing through the biographies of authors. Indispensable for scholars and students of pre-modern Chinese literature, history, and thought. Part Three contains Xia - Y. Part Four contains the Z and an extensive index to the four volumes.
The Jianghan Plain in central China has been shaped by its relationship with water. Once a prolific rice-growing region that drew immigrants to its fertile paddy fields, it has, since the eighteenth century, become prone to devastating flooding and waterlogging. Over time, population pressures and dike building left more and more people in the region vulnerable to frequent water calamities. The first environmental and socioeconomic history of the region, Coping with Calamity considers the Jianghan Plain's volatile environment, the constant challenges it presented to peasants, and their often ingenious and sophisticated responses during the Qing and Republican periods.

The book is the volume of “The Military History of Wei, Jin, Southern and Northern Dynasty ” among a series of books of “Deep into China Histories”. The earliest known written records of the history of China date from as early as 1250 BC, from the Shang dynasty (c. 1600–1046 BC) and the Bamboo Annals (296 BC) describe a Xia dynasty (c. 2070–1600 BC) before the Shang, but no writing is known from the period The Shang ruled in the Yellow River valley, which is commonly held to be the cradle of Chinese civilization. However, Neolithic civilizations originated at various cultural centers along both the Yellow River and Yangtze River. These Yellow River and Yangtze civilizations arose...
The Twenty-Four Histories (Chinese: 二十四史) are the Chinese official historical books covering a period from 3000 BC to the Ming dynasty in the 17th century. The Han dynasty official Sima Qian established many of the conventions of the genre. Starting with the Tang dynasty, each dynasty established an official office to write the history of its predecessor using official court records. As fixed and edited in the Qing dynasty, the whole set contains 3213 volumes and about 40 million words. It is considered one of the most important sources on Chinese history and culture. The title "Twenty-Four Histories" dates from 1775 which was the 40th year in the reign of the Qianlong Emperor. This ...
