Infrared and Millimeter Waves V12


Book Description

Infrared and Millimeter Waves, Volume 12: Electromagnetic Waves in Matter, Part II compiles the work of several authors while focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. This volume covers electromagnetic waves in matter. Consist of six chapters, this book deals first with the millimeter-wave dielectric properties of materials, and then discusses low-frequency vibrations in long-chain molecules and polymers by far-infrared spectroscopy. The third chapter covers infrared magnetooptical spectroscopy in semiconductors and magnetic materials in high pulsed magnetic fields. Chapter 4 discusses spectral thermal infrared emission of the terrestrial atmosphere. Chapter 5 investigates frequency tuning and efficiency enhancement of high-power far-infrared lasers, while the last chapter discusses far-infrared laser scanner for high-voltage cable inspection. This book will be of great use to researchers or professionals whose work involves infrared and millimeter waves.










Quasi-Optical Control of Intense Microwave Transmission


Book Description

Between February 17 and 20, 2004, approximately fifty scientists from ten countries came together at the Institute of Applied Physics (IAP), Nizhny Novgorod, Russia to participate in a NATO sponsored Advanced Research Workshop whose appellation is re flected in the title of this volume, namely Quasi Optical Control of Intense Microwave Transmission. The fashionable label “quasi optical ” has come into use in recent decades to denote structures whose characteristic dimensions exceed (sometimes by large factors) the free space radiation wavelength. Such structures were and are developed to replace the traditional single eigenmode ones in situations when high frequenc ies (short wavelengths) are combined with high powers, a combination that could otherwise lead to RF breakdown and high Ohmic wall heating rates. Treatments of guided wave propagation in oversized structures is aimed at pr eserving the propagating field coherence and thus to provide efficient transmission of RF power to remote destinations such as antennas, microwave ovens, plasma chemical reactors, nuclear fusion machines, and the like.




Infrared and Millimeter Waves


Book Description

Infrared and Millimeter Waves, Volume 1: Sources of Radiation explores modern sources of radiation available for use in the far-infrared and near-millimeter wavelength range of the spectrum. This book describes the operating principles and comparative performances of all three types of device: electron tubes, solid state devices, and optically pumped lasers. This volume is comprised of seven chapters; the first of which reviews the developments in the design and construction of high-power, high-efficiency millimeter sources and in the nonlinear theory for cyclotron masers. The second chapter deals with IMPATT devices for millimeter-wave power generation, with emphasis on device physics design considerations as well as cw and pulsed operations of IMPATT oscillators and amplifiers at millimeter frequencies. The chapters that follow focus on optically pumped lasers, backward wave oscillators, the Ledatron, and infrared and submillimeter-wave waveguides. This book concludes with a discussion on free electron lasers based on stimulated scattering from relativistic electron beams. An original reformulation of stimulated scattering theory that attempts to encompass all previous treatments is described and compared with available experimental data. This text also presents a semi-qualitative analysis of nonlinear saturation. This book will appeal to scientists and professional engineers.

Infrared and Millimeter Waves V5


Book Description

Infrared and Millimeter Waves is a series of books that compiles the work of several authors, with each volume focusing on certain aspects of infrared and millimeter waves, such as sources of radiation, instrumentation, and millimeter systems. This book is the first of a two-part volume that covers the coherent sources and applications of infrared and millimeter waves. The first chapter discusses sources and applications, while the second chapter provides a comprehensive discussion about spectroscopy of molecules by far-infrared laser emission. This is followed by a discussion of stark spectroscopy and frequency tuning in optically pumped far-infrared molecular lasers. Measured performance of gyrotron oscillators and amplifiers is also covered. This book will be of great use to researchers and professionals whose work involves infrared and millimeter waves.




Reviews of Infrared and Millimeter Waves


Book Description

This is the first book in the series that is being called The Reviews of Infrared and Millimeter Waves. The series will contain the manuscripts of invited papers from conferences on this subject. This first book contains some of the invited papers from the XXth General Assembly of the Union-Radio-Scientifique Internationale, Washington, August, 1981. We were asked by the URSI Cornmittee to organize a two day symposium on millimeter and submillimeter waves This required the difficult choice of five topics which turned out to be (1) Ultra-low Noise Millimeter Wave Rec ivers (Detectors and Mixers), (2) Free Electron Maser and Gyrotron, (3) Measurements of Power and Noise Power, (4) Complex Dielectric Properties of Solids and Liquids, and (5) Radioastronomy. We have not yet collected all the m . . nuscripts and perhaps we never shall because the tine-. consur. J. ing effort required to prepare a comprehensive review nanuscript works a hardship on research scientists who are already overburdened. 've are particularly grateful, therefore, to the authors lVho have worked so hard to contribute the chapters to this book.The first four chapters contibute to the timely topic of detectors, nixers and re- ceivers. These authors: Tucker, Feldman, Rudner, Okamura, Hogg and their well-known colleagues have been among the leaders in this exciting emerging field for the past few years. The fifth chapter by Sakai and Genzel is the most comprehensive treatment of the metal mesh filter science that can be found in one place.
