The first edition of High Power Microwaves was considered to be the defining book for this field. Not merely updated but completely revised and rewritten, the second edition continues this tradition. Written from a systems perspective, the book provides a unified, coherent presentation of the fundamentals in this rapidly changing field. The p

Written at the graduate level, Generation and Application of High Power Microwaves discusses the basic physics of the generation of microwave and radiofrequency waves in the megawatt power range and the application of these ideas to a range of devices such as klystrons, gyrotrons, and free electron lasers. The book also contains chapters covering the transmission of the power through waveguides and the problems associated with mode conversion in transmission lines. The main application area covered is the heating and current drive in tokamaks and other devices for research into controlled nuclear fusion. Other applications of high power microwave technology are not neglected, and among those discussed are multiple charged ion and soft x-ray sources, electron spin resonance spectroscopy, advanced materials processing, millimeter wave radar, and supercolliders.

With an increasing number of applications in areas such as defense, particle accelerators, and power beaming, high-power microwaves represent an area of growing interest for researchers around the world. The surge in the use of high-power microwaves requires a detailed understanding of sources and related technologies. This third edition presents an overview of the fundamentals of high-power microwaves in a pedagogical style, covering topics of importance to applications. The text has been thoroughly updated, including additional problems.

" ... This study concludes that high power microwave weapons systems offer the prospect of significant offensive and defensive capabilities for all of the military services. The principal recommendations include the suggestion that the Department of Defense and the Air Force establish a High Power Microwave Systems Program Office for the purpose of developing these weapons and integrating them into the combatant commands. This systems program office should be a joint program office that involves the participation of the Army, Navy, and Marine Corps as well as other agencies. Only then will the U.S. military be able to maximize the development of microwave applications, minimize costs, and facilitate the transition of this unique technology to the military services and other government agencies. Not only should defense contractors be encouraged to develop the technical capabilities that would permit them to participate in microwave weapons programs, but this study also concludes that all U.S. military system should be hardened to protect them against the effects of microwaves."--Page v

The military has long exploited the electromagnetic frequency spectrum, first with "wireless" communications in the late 1800's, and then with the discovery of radar in the 1930's. These technologies quickly evolved into many applications in the military, including advanced early warning, detection, and weapon fire control. Scientists and engineers continued to investigate the frequency spectrum to increase power levels and to develop additional applications. The term "directed energy" was once relegated to science fiction. It would be difficult to find a science fiction novel or movie that does not address directed energy weapons. But "directed energy" is now a scientific fact of life with laser pointers, pagers, fax machines, and supermarket checkout scanners. However, one area of the directed energy spectrum that has received significantly less attention and support is high power microwave technology. In view of the relative paucity of knowledge about microwaves within the Department of Defense, this study examines the role of high power microwave technology and its applications for the defense establishment. In recent years, the modern battlefield has become a "target rich" environment for high power microwave weapons. Except for the standard rifle, gun, knife, or grenade, virtually all military equipment contains some electronics. For example, in the Gulf War, the average squad or platoon of soldiers had numerous devices, ranging from radios to Global Positioning System (GPS) receivers, which they used to provide communication and information about the battlefield.

Explore the latest research avenues in the field of high-power microwave sources and metamaterials A stand-alone follow-up to the highly successful High Power Microwave Sources and Technologies, the new High Power Microwave Sources and Technologies Using Metamaterials, demonstrates how metamaterials have impacted the field of high-power microwave sources and the new directions revealed by the latest research. It’s written by a distinguished team of researchers in the area who explore a new paradigm within which to consider the interaction of microwaves with material media. Providing contributions from multiple institutions that discuss theoretical concepts as well as experimental results in slow wave structure design, this edited volume also discusses how traditional periodic structures used since the 1940s and 1950s can have properties that, until recently, were attributed to double negative metamaterial structures. The book also includes: A thorough introduction to high power microwave oscillators and amplifiers, as well as how metamaterials can be introduced as slow wave structures and other components Comprehensive explorations of theoretical concepts in dispersion engineering for slow wave structure design, including multi-transmission line models and particle-in-cell code virtual prototyping models Practical discussions of experimental measurements in dispersion engineering for slow wave structure design In-depth examinations of passive and active components, as well as the temporal evolution of electromagnetic fields High Power Microwave Sources and Technologies Using Metamaterials is a perfect resource for graduate students and researchers in the areas of nuclear and plasma sciences, microwaves, and antennas.

Here is your one-stop source of all the important research in relativistic microwave electronics in the past two decades -- advances that have greatly enhanced both the peak power and the average power capabilities of microwave oscillators and amplifiers especially at millimeter wavelengths.

"As the Department of Defense has shifted focus to near-peer competition, there has been a push to field technologies that will offer the United States a strategic advantage. The Air Force Research Lab (AFRL) has been designing, building, and testing technologies that can provide this advantage, but many have never made it to the operational inventory. One of those technologies is Pulsed-wave High Power Microwaves (HPM). HPMS has been in development for over 30 years and has seen significant advancements in the size, weight, and power of the weapon. These weapons started as large ground based systems, but in 2012 the technology had advanced to the point that AFRL placed it on an airborne platform. Since this technology demonstration, AFRL has continued to pursue advancements in this technology. HPMs also provide an opportunity to revisit an old nuclear targeting strategy, countervalue strikes. HPMs can be used to strike targets that are vital to the survival of the nation while negating collateral damage concerns. These weapons provide a unique capability to deter potential adversaries from taking action or compelling them to stop a course of action. These weapons are the type of disruptive technology the US needs to maintain its competitive advantage."--Abstract.

Our aim in this book is to present a bird's-eye view of microwave tubes (MWTs) which continue to be important despite competitive incursions from solid-state devices (SSDs). We have presented a broad and introductory survey which we hope the readers would be encouraged to read rather than going through lengthier books, and subsequently explore the field of MWTs further in selected areas of relevance to their respective interests. We hope that the present book would motivate newcomers to pursue research in MWTs and apprise them as well as decision makers of the salient features and prospects of as well as the trends of progress in MWTs. The scope of ever expanding applications of MWTs in the high power and high frequency regime will sustain and intensify the research and development in MWTs in coming years.
