High-temperature superconducting (HTS) materials are becoming more and more attractive in the context of designing RF/microwave filters because of their lower losses and excellent performance. This book focuses on the superconducting microwave filter and its application in modern communication. It first presents the basic principles, HTS materials and processing and then introduces several types of multi-band HTS bandpass filter (BPF), discussing their properties and analyzing equivalent circuit models and their performances. This book is a valuable resource for students and researchers who are interested in wireless communication and RF/microwave design.
Ultra-wideband (UWB) technology is a radio technology that uses electromagnetic waves with a very low power spectral density occupying a bandwidth of more than 25% of a centre frequency, or more than 0.5GHz, for short-range remote sensing, high-bandwidth communications or object positioning. The detailed analyses of state-of-the-art UWB technology has shown that this technology is very interesting and promising with a great application potential. Following these facts, our book attempts to present current and emerging trends in research and development of UWB systems. The book is focused on basic components of UWB systems such as antennas, filters, photonic approach for signal processing methods, as well as on some applications of UWB systems (human target analysis, cancer detection).
What was the most influential mass medium in China before the internet reaching both literate and illiterate audiences? The answer may surprise you...it’s Jingju (Peking opera). This book traces the tradition’s increasing textualization and the changes in authorship, copyright, performance rights, and textual fixation that accompanied those changes.
Emphasizing reference works published since 1964, these volumes cover books, periodicals, and inclusions (i.e., chapters in edited volumes) on the 1911 Revolution, the Republic of China (1949--), post-1911 Taiwan, post-1911 Hong Kong and Macao, and post-1911 overseas Chinese.
NEXT-GENERATION ANTENNAS: ADVANCES AND CHALLENGES The first book in this exciting new series, written and edited by a group of international experts in the field, this exciting new volume covers the latest advances and challenges in the next generation of antennas. Antenna design and wireless communication has recently witnessed their fastest growth period ever in history, and these trends are likely to continue for the foreseeable future. Due to recent advances in industrial applications as well as antenna, wireless communication, and 5G technology, we are witnessing a variety of developing and expanding new technologies. Compact and low-cost antennas are increasing the demand for ultra-wid...
Offering recent scholarship in Chinese historiography, this text focuses on radical, even revolutionary, changes of the period 1895-1912. The book investigates intellectual and institutional changes associated with the government's Xinzheng or New Systems reforms.
A Contemporary History of the Chinese Zheng traces the twentieth- and twenty-first-century development of an important Chinese musical instrument in greater China.The zheng was transformed over the course of the twentieth century, becoming a solo instrument with virtuosic capacity. In the past, the zheng had appeared in small instrumental ensembles and supplied improvised accompaniments to song. Zheng music became a means of nation-building and was eventually promoted as a marker of Chinese identity in Hong Kong. Ann L. Silverberg uses evidence from the greater China area to show how the narrative history of the zheng created on the mainland did not represent zheng music as it had been in th...
