"Following in the footsteps of its popular predecessors, High Power Microwaves, Third Edition continues to provide a wide-angle, integrated view of the field of high power microwaves (HPMs). This third edition includes significant updates in every chapter as well as a new chapter on beamless systems that covers nonlinear transmission lines. Written by an experimentalist, a theorist, and an applied theorist, respectively, the book offers complementary perspectives on different source types. The authors address: how HPM relates historically and technically to the conventional microwave field; the possible applications for HPM and the key criteria that HPM devices have to meet in order to be applied; how high power sources work, including their performance capabilities and limitations; [and] the broad fundamental issues to be addressed in the future for a wide variety of source types. The book is accessible to several audiences. Researchers currently in the field can widen their understan
