Infrared and Millimeter Waves, Volume 11: Millimeter Components and Techniques, Part III 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 millimeter components and techniques. The first chapter is a review of indium phosphide and gallium arsenide transferred-electron devices, while the next chapter covers nonradiative dielectric waveguide. Chapter 3 discusses groove guide for short millimetric waveguide systems. This book then tackles the application of oversized cavities for millimeter-wave spectroscopy, and Chapter 5 discusses powerful gyrotrons. Chapter 6 covers some perspectives on operating frequency increase in gyrotrons; Chapter 7 covers phase noise and AM noise measurement in the frequency domain. The last chapter discusses the basic design considerations for free-electron lasers driven by electron beams from rf. This book will be of great use to researchers or professionals whose work involves infrared and millimeter waves.

Infrared and Millimeter Waves, Volume 15: Millimeter Components and Techniques, Part VI is concerned with millimeter-wave guided propagation and integrated circuits. This book covers low-noise receiver technology for near-millimeter wavelengths; dielectric image-line antennas; EHF satellite communications (SATCOM) terminal antennas; and semiconductor antennas for millimeter-wave integrated circuits. A scanning airborne radiometer for 30 and 90 GHz and a self-oscillating mixer are also described. This monograph is comprised of six chapters and begins with a discussion on the design of low-noise receivers, with emphasis on problems encountered at near-millimeter wavelengths. Optimization of the material parameters and device topology for both Schottky-barrier diodes and superconducting mixer elements are considered. Some representative examples of state-of-the-art mixers and receivers, designed to operate at frequencies of 100-1000 GHz, are given in order to illustrate the way in which practical, high-performance millimeter-wave devices can be constructed. The following chapters focus on a scanning airborne radiometer for 30 and 90 GHz; a self-oscillating mixer; dielectric image-line antennas; and EHF SATCOM terminal antennas. The final chapter is devoted to semiconductor dipole antennas for millimeter-wave sensors, with particular reference to the basic concepts leading to the development of semiconductor dipoles. A theoretical formulation for tubular semiconductor dipoles is outlined and numerical results are presented to assess their characteristics. This text will be a valuable resource for physicists and electronics and electrical engineers.

Infrared and Millimeter Waves, Volume 14: Millimeter Components and Techniques, Part V is concerned with millimeter-wave guided propagation and integrated circuits. In addition to millimeter-wave planar integrated circuits and subsystems, this book covers transducer configurations and integrated-circuit techniques, antenna arrays, optoelectronic devices, and tunable gyrotrons. Millimeter-wave gallium arsenide (GaAs) IMPATT diodes are also discussed. This monograph is comprised of six chapters and begins with a description of millimeter-wave integrated-circuit transducers, focusing on various designs and trade-offs and providing hardware examples. The next chapter deals with millimeter-wave planar integrated circuits based on three transmission media: microstrip lines, suspended strip lines, and fin lines. Various transmission media and substrates are first considered, followed by design considerations and performances of several integrated-circuit components, including mixers, IMPATT oscillators, frequency multipliers, switches, filters, couplers, and ferrite devices. A few selected subsystems are also discussed. The following chapters look at planar millimeter-wave antenna arrays; optoelectronic devices for millimeter waves; and the state of the art in GaAs IMPATT diode technology for both cw and pulsed modes of operation. The final chapter is devoted to the gyrotron or electron cyclotron resonance maser. This text will be a useful resource for physicists and electronics and electrical engineers.
