A young apprentice to an assassin becomes embroiled in a conspiracy that could destroy a kingdom in a brilliant epic fantasy debut by David Gemmell Award-nominated author RJ Barker To catch an assassin, use an assassin... Girton Club-foot has no family, a crippled leg, and is apprenticed to the best assassin in the land. He's learning the art of taking lives, but his latest mission tasks him with a far more difficult challenge: to save a life. Someone is trying to kill the heir to the throne, and it is up to Girton to uncover the traitor and prevent the prince's murder. In a kingdom on the brink of civil war and a castle thick with lies, Girton finds friends he never expected, responsibilities he never wanted, and a conspiracy that could destroy an entire kingdom. Praise for The Wounded Kingdom: "Dead gods, dread magic, and a lead that feels like a breath of fresh air. Great fun." Peter Newman, author of The Vagrant "Often poignant and always intriguing, Age of Assassins reveals its mysteries with the style of a magic show and the artful grace of a gifted storyteller." Nicholas Eames, author of Kings of the Wild "The most interesting treatment of the fantasy assassin trope in a while, and an involving narrative in its own right."

Atmospheric-pressure plasmas continue to attract considerable research interest due to their diverse applications, including high power lasers, opening switches, novel plasma processing applications and sputtering, EM absorbers and reflectors, remediation of gaseous pollutants, excimer lamps, and other noncoherent light sources. Atmospheric-pressure plasmas in air are of particular importance as they can be generated and maintained without vacuum enclosure and without any additional feed gases. Non-Equilibrium Air Plasmas at Atmospheric Pressure reviews recent advances and applications in the generation and maintenance of atmospheric-pressure plasmas. With contributions from leading international researchers, the coverage includes advances in atmospheric-pressure plasma source development, diagnostics and characterization, air plasma chemistry, modeling and computational techniques, and an assessment of the status and prospects of atmospheric-pressure air plasma applications. The extensive application sections make this book attractive for practitioners in many fields where technologies based on atmospheric-pressure air plasmas are emerging.

Electrical Engineering High-Power Microwave Sources and Technologies A volume in the IEEE Press Series on RF and Microwave Technology Roger D. Pollard and Richard Booton, Series Editors Written by a prolific group of leading researchers, High-Power Microwave Sources and Technologies focuses primarily on the high-power microwave (HPM) technology most appropriate for military applications. It highlights the advances achieved from 1995 to 2000 as the result of a US Department of Defense (DoD) funded, $15 million Multidisciplinary University Research Initiative (MURI) program. The grant created a synergy between researchers in the DoD laboratories and the academic community, and established links with the microwave vacuum electronics industry, which has led to unprecedented collaborations that transcend laboratory and disciplinary boundaries. This essential reference provides the history, state-of-the-art, and possible future of HPM source research and technologies. The first alternative to the multiplicity of detailed applications-based HPM books and journal articles, this book familiarizes the reader with recent advances in this rapidly changing field. It presents a compendium of valuable information on HPM sources, representing significant enabling technologies, including beam and rf control, cathodes, windows, and computational techniques. The era of utilizing computational techniques to electronically design an HPM source prior to actually building the hardware has arrived. Gain insight into proven techniques and solutions that will enhance your source design. High-Power Microwave Sources and Technologies is an invaluable resource to researchers active in the field, faculty, graduateand post-graduate students. Special Note: All royalties realized from the sale of this book will fund the future research and publications activities of graduate students in the HPM field.

A comprehensive study of microwave vacuum electronic devices and their current and future applications

While both vacuum and solid-state electronics continue to evolve and provide unique solutions, emerging commercial and military applications that call for higher power and higher frequencies to accommodate massive volumes of transmitted data are the natural domain of vacuum electronics technology. "Modern Microwave and Millimeter-Wave Power Electronics" provides systems designers, engineers, and researchers-especially those with primarily solid-state training-with a thoroughly up-to-date survey of the rich field of microwave vacuum electronic device (MVED) technology.

This book familiarizes the R&D and academic communities with the capabilities and limitations of MVED and highlights the exciting scientific breakthroughs of the past decade that are dramatically increasing the compactness, efficiency, cost-effectiveness, and reliability of this entire class of devices.
This comprehensive text explores a wide range of topics:

• Traveling-wave tubes, which form the backbone of satellite and airborne communications, as well as of military electronic countermeasures systems
• Microfabricated MVEDs and advanced electron beam sources
• Klystrons, gyro-amplifiers, and crossed-field devices
• "Virtual prototyping" of MVEDs via advanced 3-D computational models
• High-Power Microwave (HPM) sources
• Next-generation microwave structures and circuits
• How to achieve linear amplification
• Advanced materials technologies for MVEDs
• A Web site appendix providing a step-by-step walk-through of a typical MVED design processConcluding with an in-depth examination of emerging applications and future possibilities for MVEDs, "Modern Microwave and Millimeter-Wave Power Electronics" ensures that systems designers and engineers understand and utilize the significant potential of this mature, yet continually developing technology.

SPECIAL NOTE: All of the editors' royalties realized from the sale of this book will fund the future research and publication activities of graduate students in the vacuum electronics field.
