Book Description
The Traveling Wave Tubes (TWT) is a powerful vacuum electronic device used to amplify radio-frequency (RF) signals as well as numerous applications such as radar, television and telephone satellite communications. This monograph is devoted to the author's original theoretical developments in the theory of a traveling wave tube (TWT).Most of the monograph is the author's original work on an analytical theory of TWTs. It is a constructive Lagrangian field theory of TWT in which the electron beam (e-beam) is represented by one-dimensional multi-stream electron flow and the guiding slow-wave structure is represented by possibly non-uniform multi-transmission line (MTL). The proposed analytic theory accounts for a number of electron plasma phenomena including space-charge effects such as electron-to-electron repulsion (debunching), convective instabilities, wave-particle interaction, amplifying waves and more. It allows, in particular, to (i) identify origins of the wave-particle interaction and the system convective instability (exponential growth); (ii) evaluate the energy transfer rate from the e-beam to the electromagnetic radiation; (iii) identify instability modal branches which under condition of sufficiently strong coupling between the e-beam and the MTL can cover ideally all frequencies.

High Power Microwave Sources and Technologies Using Metamaterials
Author: John W. Luginsland
Publisher: John Wiley & Sons
ISBN: 111938446X
Category : Technology & Engineering
Languages : en
Pages : 306
Book Description
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.
