Book Description
Millimeter-Wave Waveguides is a monograph devoted to open waveguides for millimeter wave applications. In the first chapters, general waveguide theory is presented (with the emphasis on millimeter wave applications). Next, the book systematically describes the results of both theoretical and experimental studies of rectangular dielectric rod waveguides with high dielectric permittivities. Simple and accurate methods for propagation constant calculations for isotropic as well as anisotropic dielectric waveguides are described. Both analytical and numerical approaches are covered. Different types of transitions have been simulated in order to find optimal configurations as well as optimal dimensions of dielectric waveguides for the frequency band of 75-110 GHz. Simple and effective design is presented. The experimental studies of dielectric waveguides show that Sapphire waveguide can be utilized for this frequency band as a very low-loss waveguide. Design of antennas with low return loss based on dielectric waveguides is also described.

Book Description
The Essence of Dielectric Waveguides provides an overview of the fundamental behavior of guided waves, essential to finding and interpreting the results of electromagnetic waveguide problems. Clearly and concisely written as well as brilliantly organized, this volume includes a detailed description of the fundamentals of electromagnetics, as well as a new discussion on boundary conditions and attenuation. It also covers the propagation characteristics of guided waves along classical canonical dielectric structures – planar, circular cylindrical, rectangular and elliptical waveguides. What’s more, the authors have included extensive coverage of inhomogeneous structures and approximate methods, as well as several powerful numerical approaches specifically applicable to dielectric waveguides.

Book Description
The millimeter-wave frequency band (30–300 GHz) is considered a potential candidate to host very high data rate communications. First used for high capacity radio links and then for broadband indoor wireless networks, the interest in this frequency band has increased as it is proposed to accommodate future 5G mobile communication systems. The large bandwidth available will enable a number of new uses for 5G. In addition, due to the large propagation attenuation, this frequency band may provide some additional advantages regarding frequency reuse and communication security. However, a number of issues have to be addressed to make mm-wave communications viable. This book collects a number of contributions that present solutions to these challenges.

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.

Book Description
Topics in Millimeter Wave Technology, Volume 1 presents topics related to millimeter wave technology, including fin-lines and passive components realized in fin-lines, suspended striplines, suspended substrate microstrips, and modal power exchange in multimode fibers. A miniaturized monopulse assembly constructed in planar waveguide with multimode scalar horn feeds is also described. This volume is comprised of five chapters; the first of which deals with the analysis and synthesis techniques for fin-lines as well as the various passive components realized in fin-line. Tapers, discontinuities, directional couplers, filters, and non-reciprocal devices are considered, along with attenuators, switches, detectors, phase modulators, mixers, and oscillators. The second chapter focuses on millimeter-wave planar integrated circuit filters, with particular reference to lowpass filter design that forms the basis for the bandpass filter design. The third chapter describes H-plane millimeter-wave planar transmission lines and circuits, along with various passive and active components realized using suspended substrate microstrips. The fourth chapter examines modal power dynamics and transmission characteristics of multimode optical fibers. The relation between a ray theory and a wave theory is also explained, and a theory of mode coupling and the modal power exchange is discussed. The book concludes with a chapter on planar waveguide versions of the classic dual-plane, amplitude-monopulse comparator realized in conjunction with a unique multimode scalar feed horn. This book will be of interest to students and practitioners of electronics and electrical engineering.
