Book Description
Advances in Microwaves, Volume 2 focuses on the developments in microwave solid-state devices and circuits. This volume contains six chapters that also describe the design and applications of diplexers and multiplexers. The first chapter deals with the parameters of the tunnel diode, oscillators, amplifiers and frequency converter, followed by a simple physical description and the basic operating principles of the solid state devices currently capable of generating coherent microwave power, including transistors, harmonic generators, and tunnel, avalanche transit time, and diodes. The next chapters discuss the characteristics of cooled parametric amplifiers; effective input noise temperature, gain-bandwidth product; gain stability, shot noise and varactor heating; and design and analysis principles of varactor harmonic generators. A chapter surveys the theory, design, and applications of diplexers and multiplexers. The concluding chapter treats the numerical solution of broad classes of problems that arise in the use of TEM-mode transmission lines.

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 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.

Book Description
The efficient design of microwave food products and associated packaging materials for optimum food quality and safety requires knowledge of product dielectric properties and associated heating mechanisms, careful consideration of product geometry, knowledge of modern packaging and ingredient technologies, and application of computer simulation, statistics and experimental design. Integrated knowledge and efficient application of these tools is essential for those developing food products in this demanding field.Development of packaging and products for use in microwave ovens provides a focused and comprehensive review for developers. Part one discusses the principles of microwave heating and ovens, with an emphasis on the effect of food dielectric properties and geometry on heating uniformity and optimising the flavours and colours of microwave foods. Microwave packaging materials and design are discussed in Part two; chapters cover rigid packaging, susceptors and shielding. Product development, food, packaging and oven safety is the topic of Part three. Computer modelling of microwave products and active packaging is discussed in Part four.Written by a distinguished team of international contributors, Development of packaging and products for use in microwave ovens is a valuable resource for those in the food and packaging industries. - Comprehensively reviews the principles of microwave heating and ovens assessing the effect of food dielectric properties on heating uniformity - Thoroughly reviews microwave packaging materials and design including testing and regulatory issues - Features a seven page section of colour diagrams to show heat distributions

Book Description
Prometheus brought fire to mankind Arthur R. von Hippel “Dielectrics and Waves”, 1954 Our contribution? There are only few areas of research and development of a comparable scientific and technological extension as microwave and high frequency processing. “Pr- essing” means not only application of radiation of 300 MHz to 300 GHz f- quency to synthesis, heating or ionisation of matter but also generation, transm- sion and detection of microwave and radio frequency radiation. Microwave and high frequency sources positioned in the orbit are the foun- tion of modern satellite telecommunication systems, gyrotron tubes being pr- ently developed in different countries all over the world will most probably be the major devices to open up a new era of energy supply to mankind be means of - sion plasma. Although initiated by military purposes during the Second World War (RADAR, Radio Detection and Ranging), microwave and high frequency utilisation has spread over almost every important aspect of normal day life since than, from individual mobile phones and kitchen microwave ovens to industrial food processing, production of composites as sustainable building materials, green chemistry, medical applications and finally infrastructure installations like GPS and Galileo, to name only few examples. These different areas of microwave and high frequency radiation application can not be unified within one group of scientists and technologists. There are s- eral distinguished communities active e.g., in the area of telecommunication s- tems, strong microwaves for fusion plasma or plasma based materials processing.
