Advances in Microwaves


Book Description

Advances in Microwaves, Volume 8 covers the developments in the study of microwaves. The book discusses the circuit forms for microwave integrated circuits; the analysis of microstrip transmission lines; and the use of lumped elements in microwave integrated circuits. The text also describes the microwave properties of ferrimagnetic materials, as well as their interaction with electromagnetic waves propagating in bounded waveguiding structures. The integration techniques useful at high frequencies; material technology for microwave integrated circuits; specific requirements on technology for distributed and lumped-element circuits; and characterization and utilization of solid-state devices in integrated circuits are also encompassed. The book further tackles microwave propagation on coupled pairs of microstrip transmission lines and computer-aided design, simulation and optimization of microwave technology. Microwave engineers will find the book invaluable.

Book Description

Advances in Microwaves, Volume 3 covers the advances and applications of microwave signal transmission and Gunn devices. This volume contains six chapters and begins with descriptions of ground-station antennas for space communications. The succeeding chapters deal with beam waveguides, which offer interesting possibilities for transmitting microwave energy, as well as with parallel or tubular beams from antenna apertures. A chapter discusses the electron transfer mechanism and the velocity-field characteristics, with a particular emphasis on the microwave properties of Gunn oscillators. The last chapters survey the specific physical and operating characteristics of the various high power amplifiers and oscillators, which have been developed for operation at millimeter wavelengths. These chapters also examine the nonlinear interactions of spin waves and elastic waves.

Book Description

Advances in Microwaves, Volume 4 covers some innovations in the devices and applications of microwaves. This volume contains three chapters and begins with a discussion of the application of microwave phasers and time delay elements as beam steering elements in array radars. The next chapter provides first an overview of the technical aspects and different types of millimeter waveguides, followed by a survey of their application to railroads. The last chapter examines the general mode of conversion properties of nonuniform waveguides, such as waveguide tapers, using converted Maxwell’s equations, with appropriate boundary conditions, into generalized telegraphist’s equations.

Advances in Microwaves, Volume 7 covers the developments in the study of microwaves. The book discusses the effect of surface roughness on the propagation of the TEM mode, as well as the voltage breakdown of microwave antennas. The text also describes the theory and design considerations of single slotted-waveguide linear arrays and the techniques and theories that led to the achievement of wide bandwidths and ultralow noise temperatures for communication applications. The book will prove invaluable to microwave engineers.







Advances in Microwaves V5


Book Description

Advances in Microwaves, Volume 5 is a three-chapter text that covers low microwave frequencies used to accelerate elementary particles and centimeter and millimeter waves for exploring atmospheric phenomena, as well as the microwave demodulation of light. Chapter 1 describes high-speed photodetectors whose modulation frequency response extends into the microwave region. This chapter focuses on the fundamental principles of specific detectors whose performance is sufficiently close to fundamental limits to assure their staying power. Chapter 2 examines radiometric fundamentals associated with the frequency spectrum, with particular emphasis on the 3 cm to 3 mm wavelength region. Chapter 3 discusses the conditions in which hybrid waves traveling at the velocity of light can exist in a homogeneous isotropic medium. This chapter also explores the design requirements of deflectors. Discussions on transformation of Maxwell’s equations for a traveling wave in a gyroelectric or gyromagnetic medium and consistent solutions of the scalar wave equation are provided in the supplementary texts.




Advances in Microwaves


Book Description

Advances in Microwaves, Volume 1 is a collection of papers dealing with the design and fabrication of a two-mile accelerator, optical waveguides, and directional couplers. One paper describes the design and fabrication of the disk-loaded wave guide, which serves as the accelerating structure, of the Stanford two-mile accelerator. Another paper discusses the basic principles of guided propagation, particularly the properties of the confocal lens systems or the "beam guide" variants. One paper describes the main types of directional couplers (namely, waveguide directional couplers, TEM-Mode directional couplers) to help scientists and researchers determine a particular design. Some papers discuss singular integral equations to solve waveguide problems, the application of Lie algebraic theory to microwave networks, and partially filled waveguides and surface waveguides of rectangular cross section. One paper explains the application of the singular integral equation method to rectangular waveguides, including the infinite parallel plate configuration. Another paper cites the exponentially tapered transmission line as an example to show the application of Lie algebras in solving problems related to the microwave field. The collection is suitable for people in the field of applied mathematics, nuclear physics, quantum mechanics, and applied physics.
