The instrumentation and design of high power microwave sources

Abstract

The application horizon of microwave based devices is ever expanding in diverse fields like defense, telecommunication, navigation etc. Microwave devices have played an important role in a variety of fields which includes accelerators, magnetic confinement fusion, communication, earth and space observations and military applications. Military use of microwave devices covers radar, communication, electronic warfare, electronic counter-measures and testing. Recently, efforts have been made to develop techniques to generate high-power microwave and analysis its linear and nonlinear propagation through dielectric media. A whole new branch of physics evolves to explore the high-power microwave (HPM) devices. Broadly, HPM includes analysis of microwave and millimeter waves which frequencies lie in the range of 1-100 GHz and having peak power >100MW. In general, these waves are considered to be either pulse of long duration with high pulse repetition frequency (PRF), or continuous wave. Additionally, the high peak power, pulse of short duration and low PRF is also considered for HPM. HPM devices are proposed to be used in a variety of civilian and defense applications. © 2017 by Nova Science Publishers, Inc. All rights reserved.
