Book Description
Nonlethal weapons are going to play an increasingly important role in combat and in civil conflict in the coming years. They offer a way of controlling dissent and insurgencies without increasing antagonism, particularly in peacekeeping operations. They prevent the unnecessary loss of life among the non-combatant population of adversaries and they decrease the number of casualties due to friendly fire. The need for new nonlethal weapons technologies has been well documented by researchers and policymakers. High-powered electromagnetic radiators are aimed at addressing that need. Beginning with a brief survey of the history of warfare, D. V. Giri systematically examines various nonlethal weapons technologies, emphasizing those based on electromagnetics. His systematic review of high-power electromagnetic radiators is organized by frequency, coverage, and level of sophistication of underlying technologies. He provides many examples of complete systems, going from wall-socket to radiated waves. Giri's focus on electromagnetics makes this book essential reading for researchers working with high-power microwave and electromagnetic pulse technologies as well as antenna engineers.

Book Description
Pulses with sub-nanoseconds / nanoseconds rise time are used in high power radar, sterilization, testing the effect on electronic systems, food irradiation, electromagnetic welding, forming, wastewater processing, defence, medical electronics, etc. There are various methods for obtaining the mentioned low rise time pulses. In this book, a Marx generator, peaking capacitor and peaking switch are used to obtain high amplitude low rise time pulse. A radiating antenna is then connected to the output of peaking stage. Such a system is known as the high-power electromagnetic (EM) impulse radiator. Two such EM radiators were mathematically analysed, simulated, designed, fabricated and the experiments have been conducted in this book.

Book Description
This is the first book that comprehensively addresses the issues relating to the effects of radio frequency (RF) signals and the environment of electrical and electronic systems. It covers testing methods as well as methods to analyze radio frequency. The generation of high-powered electromagnetic (HPEM) environments, including moderate band damped sinusoidal radiators and hyperband radiating systems is explored. HPEM effects on component, circuit, sub-system electronics, as well as system level drawing are discussed. The effects of HPEM on experimental techniques and the standards which can be used to control tests are described. The validity of analytical techniques and computational modeling in a HPEM effects context is also discussed. Insight on HPEM effects experimental techniques and the standards which can be used to control tests is provided, and the validity of analytical techniques and computational modeling in a HPEM effects context is discussed. This book dispels myths, clarifies good experimental practice and ultimately draws conclusions on the HPEM interaction with electronics. Readers will learn to consider the importance of HPEM phenomena as a threat to modern electronic based technologies which underpin society and to therefore be pre-emptive in the consideration of HPEM resilience.

Book Description
This book presents a unique and comprehensive introduction to performance prediction of directed energy (DE) systems using mathematical modeling frameworks, with focus on high power radio frequency and high energy laser performance. It provides system designers with a means for predicting DE system performance and measuring the required power levels necessary to neutralize targets including UAVs and other unmanned swarms. The book begins with a systematic and concise overview of DE systems, including its historical roots. You will then learn how to develop effective mathematical models and understand how to use these models to implement safer and efficient use of DE systems in various scenarios. A special section is devoted to examples and attributes of unmanned systems since these are viewed as primary targets suitably disabled by DE systems. There is also an extensive survey of the relevant tools of mathematics and physics for DE systems, together with a series of pertinent references you can follow for further information. The final section of the book outlines potential future research directions that interested researchers are encouraged to pursue. With its exclusive and unmatched coverage of predictive modeling for DE systems and performance, this is an important book for engineers and operators working in the defense industry, including government and private contractors, as well as research practitioners at universities and engineering organizations worldwide working in the field of DE system performance.
