The physical properties of the ionized layer in the Earth's upper atmosphere enable us to use it to support an increasing range of communications applications. This book presents a modern treatment of the physics and phenomena of the high latitude upper atmosphere and the morphology of radio propagation in the auroral and polar regions. Chapters cover the basics of radio propagation and the use of radio techniques in ionospheric studies. Many investigations of high latitude radio propagation have previously only been published in Conference Proceedings and organizational reports. This book includes many examples of the behavior of quiet and disturbed high latitude HF propagation. Ample cross-referencing, chapter summaries and reference lists make this book an invaluable aid for graduate students, ionospheric physicists and radio engineers.

This practical text gives engineers and technicians at all levels an easy-to-follow entry point into the subject of RF/EM wave propagation and antennas. While aimed primarily at those who are entering the field or transitioning from a related field, the book also helps experienced professionals obtain a more refined understanding of the various methodologies and processes in this area. The book covers the essentials, practices, technical details, and considerations needed to help a team of engineers design, install, and/or predict the technical performance of a new (or even existing) one-way, two-antenna (long radiating distance) RF communication system. The chapters are organized logically to walk you step by step through the application processes, showing you proven methods to bring about top performance, while also helping you factor in unanticipated variances, including those caused by the earth itself, earth’s gaseous atmosphere, rain, snow, hail, ice, ionospheric signal attenuation, and EM waves. This kind of understanding and consideration saves time, money, and much frustration in a project. With this book in hand, you will better understand RF/EM wave propagation and the technical vernacular used to describe it; become familiar with the various processes and considerations in analyzing, designing, and predicting the performance of new and existing antenna RF communications systems; and more confidently approach problem solving and possible solutions for reducing signal interference and loss. The chapter contents, while not sparing the reader exposure to radiated RF system design and analysis terminology, are written in a relaxed, conversational tone and easy-to-understand manner, making this a perfect learning tool for those entering or transitioning to this field, as well as an excellent supplement or foundational text for an instructional course. The book’s logically organized and easy-to-access chapter structure also facilitates its use as a bench reference for quick lookup or review.

This book presents a practical design method for cellular systems, focusing on antenna design and propagation in different scenarios, with particular emphasis on base station (BS) and mobile terminals. Written by an expert in antenna measurement for mobile systems, the book fully details the fundamentals of and design considerations for both antennas and propagation, which is not commonly found together in one resource. The book helps you understand the practical design procedures of mobile communication antenna systems based on the propagation estimation by measurements and simulation. You will learn all the required knowledge and background for the research and development of current and future systems, and a host of other essential considerations and conditions pertaining to antenna and propagation. This is an excellent book for engineers working for cellar system operators, engineers working for manufacturing companies of smart phones and base station systems, and graduate students majoring antennas and propagation.

This practical book provides fundamentals of electromagnetic wave propagation and its unique application for the design of mobile wireless systems in complex urban environments. It supplies telecommunication engineers with the proper theoretical and practical tools to: plan radio coverage in cellular networks; design a radio link; predict connectivity in a wireless network and ensure that the system to be designed fulfills regulations on exposure of general public to electromagnetic fields. You'll understand the latest propagation models and be equipped to address the challenges facing wireless propagation for the most recent 5G mobile systems, including how to cope with new propagation scenarios/frequencies in 5G wireless channel modelling. You'll also find unique coverage of the problems of human exposure to electromagnetic fields and the corresponding international and national regulations, including the most recent ICNIRP guidelines. The book brings theory, algorithms, and applications into focus with some practical examples. Specific attention is devoted to laying the mathematical foundations of the asymptotic techniques that are presented; of the propagation over a flat and spherical Earth; and also of the propagation in complex environment in order to provide a cohesive exposition of the underlying principles. With its strong theoretical background on fundamentals of electromagnetic propagation along with an application-oriented approach, this is a must-have book for researchers working on applied electromagnetics and engineers working on wireless network planning at an advanced level. It is also rich in details and clear, making it an excellent textbook for advanced and graduate-level students.

In the recent decades, there has been a growing interest in micro- and nanotechnology. The advances in nanotechnology give rise to new applications and new types of materials with unique electromagnetic and mechanical properties. This book is devoted to the modern methods in electrodynamics and acoustics, which have been developed to describe wave propagation in these modern materials and nanodevices. The book consists of original works of leading scientists in the field of wave propagation who produced new theoretical and experimental methods in the research field and obtained new and important results. The first part of the book consists of chapters with general mathematical methods and approaches to the problem of wave propagation. A special attention is attracted to the advanced numerical methods fruitfully applied in the field of wave propagation. The second part of the book is devoted to the problems of wave propagation in newly developed metamaterials, micro- and nanostructures and porous media. In this part the interested reader will find important and fundamental results on electromagnetic wave propagation in media with negative refraction index and electromagnetic imaging in devices based on the materials. The third part of the book is devoted to the problems of wave propagation in elastic and piezoelectric media. In the fourth part, the works on the problems of wave propagation in plasma are collected. The fifth, sixth and seventh parts are devoted to the problems of wave propagation in media with chemical reactions, in nonlinear and disperse media, respectively. And finally, in the eighth part of the book some experimental methods in wave propagations are considered. It is necessary to emphasize that this book is not a textbook. It is important that the results combined in it are taken “from the desks of researchers“. Therefore, I am sure that in this book the interested and actively working readers (scientists, engineers and students) will find many interesting results and new ideas.
