Book Description
Webster’s New World Telecom Dictionary, by Ray Horak, is a comprehensive telecommunications dictionary of more than 7,500 terms critical to understanding voice, data, video, and multimedia communications system and network technologies, applications, and regulation. Given the convergence of computing and communications, the book also effectively is a computer dictionary with a telecom focus. It is thoroughly researched, highly objective, absolutely accurate, and includes just about every essential term, abbreviation, acronym, contraction, initialism, and portmanteau you might encounter in the telecom and datacom domains. Although the book is a technical dictionary, Horak’s plain-English, commonsense style yields definitions that are as thoroughly understandable to the business professional or student as they are to the electrical engineer. In fact, many entries are encyclopedic in nature, discussing applications and issues. Horak also injects a bit of his wry sense of humor, sprinkling occasional telecom trivia and marginally related definitions that will have you smiling and chuckling to yourself, but not to the point that they detract from what is an important book on a serious subject. An instant classic, Webster’s New World Telecom Dictionary is the one and only telecom dictionary you will need. It also makes a perfect companion to Horak’s Telecommunications and Data Communications Handbook, published by Wiley-Interscience in October 2007.

Book Description
"This book presents the histories of the major North American shortwave clubs and reviews the professional and listener-generated shortwave literature of the era. It also covers the DX programs and other listening fare to which shortwave listeners were most attracted and the QSL-cards they sought as confirmation of their reception."--Provided by publisher.

Book Description
This book addresses the peculiarities of nonlinear wave propagation in waveguides and explains how the stratification depends on the waveguide and confinement. An example of this is an optical fibre that does not allow light to pass through a density jump. The book also discusses propagation in the nonlinear regime, which is characterized by a specific waveform and amplitude, to demonstrate so-called solitonic behaviour. In this case, a wave may be strongly localized, and propagates with a weak change in shape. In the waveguide case there are additional contributions of dispersion originating from boundary or asymptotic conditions. Offering concrete guidance on solving application problems, this essentially (more than twice) expanded second edition includes various aspects of guided propagation of nonlinear waves as well as new topics like solitonic behaviour of one-mode and multi-mode excitation and propagation and plasma waveguides, propagation peculiarities of electromagnetic waves in metamaterials, new types of dispersion, dissipation, electromagnetic waveguides, planetary waves and plasma waves interaction.The key feature of the solitonic behaviour is based on Coupled KdV and Coupled NS systems. The systems are derived in this book and solved numerically with the proof of stability and convergence. The domain wall dynamics of ferromagnetic microwaveguides and Bloch waves in nano-waveguides are also included with some problems of magnetic momentum and charge transport.

Book Description
Provides a comprehensive discussion of planar transmission lines and their applications, focusing on physical understanding, analytical approach, and circuit models Planar transmission lines form the core of the modern high-frequency communication, computer, and other related technology. This advanced text gives a complete overview of the technology and acts as a comprehensive tool for radio frequency (RF) engineers that reflects a linear discussion of the subject from fundamentals to more complex arguments. Introduction to Modern Planar Transmission Lines: Physical, Analytical, and Circuit Models Approach begins with a discussion of waves on transmission lines and waves in material medium, including a large number of illustrative examples from published results. After explaining the electrical properties of dielectric media, the book moves on to the details of various transmission lines including waveguide, microstrip line, co-planar waveguide, strip line, slot line, and coupled transmission lines. A number of special and advanced topics are discussed in later chapters, such as fabrication of planar transmission lines, static variational methods for planar transmission lines, multilayer planar transmission lines, spectral domain analysis, resonators, periodic lines and surfaces, and metamaterial realization and circuit models. Emphasizes modeling using physical concepts, circuit-models, closed-form expressions, and full derivation of a large number of expressions Explains advanced mathematical treatment, such as the variation method, conformal mapping method, and SDA Connects each section of the text with forward and backward cross-referencing to aid in personalized self-study Introduction to Modern Planar Transmission Lines is an ideal book for senior undergraduate and graduate students of the subject. It will also appeal to new researchers with the inter-disciplinary background, as well as to engineers and professionals in industries utilizing RF/microwave technologies.
