Semiconductor Spintronics, as an emerging research discipline and an important advanced field in physics, has developed quickly and obtained fruitful results in recent decades. This volume is the first monograph summarizing the physical foundation and the experimental results obtained in this field. With the culmination of the authors' extensive working experiences, this book presents the developing history of semiconductor spintronics, its basic concepts and theories, experimental results, and the prospected future development. This unique book intends to provide a systematic and modern foundation for semiconductor spintronics aimed at researchers, professors, post-doctorates, and graduate students, and to help them master the overall knowledge of spintronics.

The second edition of Microwave Ring and Related Structures, Circuits, and Antennas incorporates the latest material on ring circuits and applications. This edition covers the following new topics: the parallel plate waveguide model, using both rectangular and circular ring configurations, and disk geometris and sprial inductors, which have wide usage in RF and microwave circuits.

This enlightening book provides the first systematic introduction to, and exploration of, the emerging system of industrial relations in China, and draws on the authors' extensive research and direct involvement in the developments taking place. The authors argue that there are both unifying and fragmenting elements to the ongoing development of industrial relations, but overall it is one in which the state continues to maintain a major, and direct, influence. Divisions between workers and managers may be escalating with increased open conflicts, but this book reveals that the picture is far more complex and contradictory than to assume that the solution is convergence with western style industrial relations systems. They conclude that industrial relations institutions and processes still act within a political context and with the guiding hand of the Chinese Communist party.Industrial Relations in China draws on up-to-date material and will ensure the book's appeal to industrial relations and Chinese scholars. It will also appeal to a wider audience of Asian labour and development studies scholars.

This is the first book to provide comprehensive coverage of hardware and circuit design specifically for engineers working in wireless communications. It serves as a reference for practicing engineers and technicians working in the areas of RF, microwaves, communications, solid-state devices, and radar.

A comprehensive introduction to the hardware, parameters, and architectures of RF/microwave wireless systems As the basis for some of the hottest technologies of the new millennium, radio frequency (RF) and microwave wireless systems rapidly propel us toward a future in which the transmission of voice, video, and data communications will be possible anywhere in the world through the use of simple, handheld devices. This book provides scientists and engineers with clear, thorough, up-to-date explanations of all aspects of RF and microwave wireless systems, including general hardware components, system parameters, and architectures. Renowned authority Kai Chang covers both communication and radar/sensor systems and extends the discussion to other intriguing topics, from global positioning systems (GPS) to smart highways and smart automobiles. With an emphasis on basic operating principles, Dr. Chang reviews waves and transmission lines, examines modulation and demodulation and multiple-access techniques, and helps bridge the gap between RF/microwave engineering and communication system design. Ample practical examples of components and system configurations and nearly 300 illustrations and photographs complete this timely and indispensable resource.

This is the only book currently available that covers this subject. The authors piece together information from diverse areas which is essential to understand integrated and integrated active antennas. Emphasis is placed on active antennas and power combining applications, consolidating the work from numerous researchers. Early chapters lay the foundation for oscillator, antenna, array and power combining theory. Chapter five discusses important testing parameters and techniques for active antenna measurements and includes definitions for equivalent isotropic radiated power, locking gain and locking bandwidth. The last chapter sheds light on beam steering, a more recent development in active antenna arrays. Contains over 200 illustrations.

Focuses on the basic operating principles and the techniques used to incorporate the devices into circuit applications. Part one reviews fundamental principles in transmission lines and circuits as well as semiconductor physics. Two-terminal solid-state devices, circuits and applications are covered in the second section. Part three discusses three-terminal solid-state devices, circuits and applications. Introduces noise figures and system parameters for receiver design. Includes numerous examples and problems.
