Book Description
Electron Dynamics of Diode Regions describes the model construction and analysis of motion of charged particles of diode regions in time-varying fields. The models analyzed are simplified versions of parts of practical devices, primarily active microwave devices, tubes, and semiconductor amplifiers, while the most striking results obtained are due to electron inertia and space-charge effects in terms of laboratory observable. This book is composed of seven chapters, and begins with an introduction to the general concepts of time dependent flow, including induced current, the techniques of linearization, calculating variational transit time, and obtaining equivalent circuits. The following chapters present the classical linear analysis, which includes the space-charge effects, with several applications. These chapters also explore the existence of a maximum stable current in a space-charge limited diode. The discussion then shifts to the basics of high velocity, klystron, gap with nonuniform field distributions, and the application of the multicavity klystron. This text further covers the analysis and examples of crossed-field gaps. The final chapters deal with the fundamentals of velocity and current distributions obtained from common electron emitters, with some attempt to show how the multivelocity streams evolve into single-velocity equivalents needed for the methods of earlier chapters. Results of applying the Lagrangian starting analysis to semiconductor diode regions, necessarily from a new equation of motion, are also provided. This book is intended for graduate courses, seminars, and research studies.

Energy Conversion Statics
Author: H. K. Messerle
Publisher: Elsevier
ISBN: 1483282236
Category : Science
Languages : en
Pages : 361
Book Description
Energy Conversion Statics deals with equilibrium situations and processes linking equilibrium states. A development of the basic theory of energy conversion statics and its applications is presented. In the applications the emphasis is on processes involving electrical energy. The text commences by introducing the general concept of energy with a survey of primary and secondary energy forms, their availability, and use. The second chapter presents the basic laws of energy conversion. Four postulates defining the overall range of applicability of the general theory are set out, demonstrating the basic importance of the stored energy function. Subsequent chapters extend the concept of the energy function as a state function; introduce transformed functions like coenergy; describe the concept of quasi-static processes; and develop general theorems for one-way and cyclic processes. The remainder of the text deals with specific fields of energy conversion and the basic theory developed in the first four chapters is used. The book is intended for students in the final year of an undergraduate course and it can be used as the basis for graduate courses in energy conversion. It may also be used as a basic text for courses in thermodynamics and electromechanics.

Analysis of Reflector Antennas
Author: W. V. T. Rusch
Publisher: Academic Press
ISBN: 1483219887
Category : Technology & Engineering
Languages : en
Pages : 191
Book Description
Analysis of Reflector Antennas provides information pertinent to the analysis of reflector-antenna systems. This book provides an understanding of how design data have been and can be derived. Organized into four chapters, this book begins with an overview of the history of focusing reflector-antenna systems characterized by a highly variable level of general interest. This text then examines the solutions of the scalar Helmholtz equation in rectangular and spherical coordinates. Other chapters consider antenna performance described in terms of several fundamental properties, including capture area, directivity, gain, beam efficiency, aperture efficiency, polarization, effective noise temperature, and phase center. This book discusses as well the resulting functional dependence between axial ratio and component amplitude, which is the same as that between voltage standing wave ratio and voltage reflection coefficient. The final chapter deals with the role of the special-purpose digital computers. This book is a valuable resource for research and development engineers.

Frequency Domain Criteria for Absolute stability
Author: Kumpati S. Narendra
Publisher: Elsevier
ISBN: 0323162347
Category : Technology & Engineering
Languages : en
Pages : 269
Book Description
Frequency Domain Criteria for Absolute Stability presents some generalizations of the well-known Popov solution to the absolute stability problem proposed by Lur'e and Postnikov in 1944. This book is divided into nine chapters that focus on the application of Lyapunov's direct method to generate frequency domain criteria for stability. The first eight chapters explore the systems with a single nonlinear function or time-varying parameter. These chapters also discuss the development of stability criteria for these systems, the sufficiency theorems, and Lyapunov function. Some of the theorems applied to a damped version of the Mathieu equation and to a nonlinear equation derived from it are also covered. The concluding chapter deals with systems with multiple nonlinearities or time-varying gains. This chapter also outlines the basic definitions and tools, as well as the derivation of stability criteria. This work will serve as a reference for research courses concerning stability problems related to the absolute stability problem of Lur'e and Postnikov. Engineers and applied mathematicians will also find this book invaluable.

Lumped and Distributed Passive Networks
Author: M. Ronald Wohlers
Publisher: Academic Press
ISBN: 1483221245
Category : Technology & Engineering
Languages : en
Pages : 247
Book Description
Lumped and Distributed Passive Networks: A Generalized and Advanced Viewpoint considers the mathematical study of a subset of passive linear operators. This five-chapter focuses on the questions of analysis and representation of such operators and illustrates the results of these analyses by obtaining some of the limitations that are imposed on the performance of passive systems. The first two chapters deal with the structure of general linear passive operators. These chapters specifically look into the theory of distributions, called generalized functions. The third and fourth chapters illustrate the application of passive operator theory to rational (lumped) and irrational (distributed) systems. The fifth chapter discusses some applications of optimization theory to the study of networks.
