Book Synopsis Radio Wave Propagation by : John A. Richards
Download or read book Radio Wave Propagation written by John A. Richards and published by Springer Science & Business Media. This book was released on 2008-01-22 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work treats the essential elements of radio wave propagation without requiring recourse to advanced electromagnetic concepts and equations. However, it provides sufficient detail to allow those concerned with wireless systems to acquire quickly a practical working knowledge of the important concepts. Radio wave propagation is placed in a practical context by considering the design aspects of communications systems at microwave frequencies. A fuller consideration of the electromagnetic properties of materials is given late in the book rather than as an introductory chapter.
Book Synopsis Looking at Time from a Physics Perspective by : Patricio Robles
Download or read book Looking at Time from a Physics Perspective written by Patricio Robles and published by CRC Press. This book was released on 2024-04-23 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of time continues to be a subject of extensive research in the development of new theories of physics. This new volume is addressed to students who are starting a graduate program in physics or electrical engineering interested in complementing their studies of relativity theory and quantum physics, applying the knowledge they have acquired about these themes to the analysis of situations where the issue of time measurement is relevant. This is the case, for example, of clock synchronization, transit times of optical signals through dielectric and absorbing media, lifetimes of excited atomic states, among others. These topics, in addition to being of great importance to theoretical physicists, are the basis of many technological developments. For example, global positional systems (GPS) are based on the predictions of relativity theory about time and the effect of gravity over time measurement. Divided into six chapters, the volume discusses how the concept of time is present in the main fields of physics, such as classical mechanics, electrodynamics, quantum mechanics and theory of relativity. Illustrative examples and case studies are included in each chapter. The volume includes an analysis of themes related to time such as causality and the arrows of time, spooky action at distance and Einstein-Podolsky-Rosen Paradox, quantum mechanics and entangled states, apparent superluminal velocity, and time reversal. This book, Looking at Time from a Physics Perspective, will contribute to the understanding of concepts learned in courses on classical mechanics, electrodynamics, quantum mechanics and relativity, reviewing the implications of the time variable for the description of the different physical phenomena at the microscopic and macroscopic level.

Download or read book Radiowave Propagation written by Curt Levis and published by John Wiley & Sons. This book was released on 2010-06-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: An accessible student-oriented approach to radiowave propagation Propagation-the process whereby a signal is conveyed between transmitter and receiver-has a profound influence on communication systems design. Radiowave Propagation provides an overview of the physical mechanisms that govern electromagnetic wave propagation in the Earth's troposphere and ionosphere. Developed in conjunction with a graduate-level wave propagation course at The Ohio State University, this text offers a balance of physical and empirical models to provide basic physical insight as well as practical methods for system design. Beginning with discussions of propagation media properties, plane waves, and antenna and system concepts, successive chapters consider the most important wave propagation mechanisms for frequencies ranging from LF up to the millimeter wave range, including: Direct line-of-sight propagation through the atmosphere Rain attenuation The basic theory of reflection and refraction at material interfaces and in the Earth's atmosphere Reflection, refraction, and diffraction analysis in microwave link design for a specified terrain profile Empirical path loss models for point-to-point ground links Statistical fading models Standard techniques for prediction of ground wave propagation Ionospheric propagation, with emphasis on the skywave mechanism at MF and HF and on ionospheric perturbations for Earth-space links at VHF and higher frequencies A survey of other propagation mechanisms, including tropospheric scatter, meteor scatter, and propagation effects on GPS systems Radiowave Propagation incorporates fundamental materials to help senior undergraduate and graduate engineering students review and strengthen electromagnetic physics skills as well as the most current empirical methods recommended by the International Telecommunication Union. This book can also serve as a valuable teaching and reference text for engineers working with wireless communication, radar, or remote sensing systems.

Book Synopsis Radio Wave Propagation and Channel Modeling for Earth-Space Systems by : Athanasios G. Kanatas
Download or read book Radio Wave Propagation and Channel Modeling for Earth-Space Systems written by Athanasios G. Kanatas and published by CRC Press. This book was released on 2017-12-19 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The accurate design of earth–space systems requires a comprehensive understanding of the various propagation media and phenomena that differ depending on frequencies and types of applications. The choice of the relevant channel models is crucial in the design process and constitutes a key step in performance evaluation and testing of earth–space systems. The subject of this book is built around the two characteristic cases of satellite systems: fixed satellites and mobile satellite systems. Radio Wave Propagation and Channel Modeling for Earth–Space Systems discusses the state of the art in channel modeling and characterization of next-generation fixed multiple-antennas and mobile satellite systems, as well as propagation phenomena and fade mitigation techniques. The frequencies of interest range from 100 MHz to 100 GHz (from VHF to W band), whereas the use of optical free-space communications is envisaged. Examining recent research advances in space-time tropospheric propagation fields and optical satellite communication channel models, the book covers land mobile multiple antennas satellite- issues and relative propagation campaigns and stratospheric channel models for various applications and frequencies. It also presents research and well-accepted satellite community results for land mobile satellite and tropospheric attenuation time-series single link and field synthesizers. The book examines aeronautical communications channel characteristics and modeling, relative radio wave propagation campaigns, and stratospheric channel model for various applications and frequencies. Propagation effects on satellite navigation systems and the corresponding models are also covered.

Book Synopsis Radiowave Propagation in Satellite Communications by : Louis J. Ippolito
Download or read book Radiowave Propagation in Satellite Communications written by Louis J. Ippolito and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiowave Propagation in Communications was written with two basic objec tives: (l) to present an up-to-date review of the major radiowave propagation phenomena which hinder reliable space communications, and (2) to describe how these propagation phenomena affect the design and performance of satellite communications systems. Earth-orbiting satellites are employed extensively for the relay of information in a vast array of telecommunications, meteorological, government, and sci entific applications. Satellite systems rely on the transmission of radiowaves to and from the satellite and are dependent on the propagation characteristics of the transmission path, primarily the earth's atmosphere. Radiowave propagation thus plays a very important part in the design and ultimate performance of space communications systems. This book presents, for the first time, the meshing in a single publication of the fundamentals of radiowave propagation factors with a discussion of the practical consequences of these factors on satellite communications systems. Two major subfie1ds are involved in this book. Radiowave propagation, which is basically applied electromagnetic theory, provides the theory and an alytical tools for the first several chapters. Later chapters then apply propagation effects to the field of electrical engineering involved with satellite communi cations. The material progresses from the essential aspects of radiowave prop agation to the application of practical methods and techniques in the design and performance of satellite communications systems.
Book Synopsis The Evolution of Untethered Communications by : National Research Council
Download or read book The Evolution of Untethered Communications written by National Research Council and published by National Academies Press. This book was released on 1998-01-01 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: In response to a request from the Defense Advanced Research Projects Agency, the committee studied a range of issues to help identify what strategies the Department of Defense might follow to meet its need for flexible, rapidly deployable communications systems. Taking into account the military's particular requirements for security, interoperability, and other capabilities as well as the extent to which commercial technology development can be expected to support these and related needs, the book recommends systems and component research as well as organizational changes to help the DOD field state-of-the-art, cost-effective untethered communications systems. In addition to advising DARPA on where its investment in information technology for mobile wireless communications systems can have the greatest impact, the book explores the evolution of wireless technology, the often fruitful synergy between commercial and military research and development efforts, and the technical challenges still to be overcome in making the dream of "anytime, anywhere" communications a reality.
Book Synopsis Wireless Communication-the fundamental and advanced concepts by : Sanjay Kumar
Download or read book Wireless Communication-the fundamental and advanced concepts written by Sanjay Kumar and published by CRC Press. This book was released on 2022-09-01 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication is one of the fastest growing fields in the engineering world today. Rapid growth in the domain of wireless communication systems, services and application has drastically changed the way we live, work and communicate. Wireless communication offers a broad and dynamic technological field, which has stimulated incredible excitements and technological advancements over last few decades. The expectations from wireless communication technology are increasing every day. This is placing enormous challenges to wireless system designers. Moreover, this has created an ever increasing demand for conceptually strong and well versed communication engineers who understand the wireless technology and its future possibilities. In recent years, significant progress in wireless communication system design has taken place, which will continue in future. Especially for last two decades, the research contributions in wireless communication system design have resulted in several new concepts and inventions at remarkable speed. A text book is indeed required to offer familiarity with such developments and underlying concepts, to be taught in the classroom to future engineers. This is one of the motivations for writing this book. Practically no book can be up to date in this field, due to the fast ongoing research and developments. The new developments are announced almost every day. Teaching directly from the research papers in the classroom cannot build the necessary foundation. Therefore need for a textbook is unavoidable, which is integral to learning, and is an essential source to build the concept. The prime goal of this book is to cooperate in the learning process.

Book Synopsis Deep Space Telecommunications Systems Engineering by : Joseph H. Yuen
Download or read book Deep Space Telecommunications Systems Engineering written by Joseph H. Yuen and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: The challenge of communication in planetary exploration has been unusual. The guidance and control of spacecraft depend on reliable communication. Scientific data returned to earth are irreplaceable, or replaceable only at the cost of another mission. In deep space, communications propagation is good, relative to terrestrial communications, and there is an opportunity to press toward the mathematical limit of microwave communication. Yet the limits must be approached warily, with reliability as well as channel capacity in mind. Further, the effects of small changes in the earth's atmosphere and the interplanetary plasma have small but important effects on propagation time and hence on the measurement of distance. Advances are almost incredible. Communication capability measured in 18 bits per second at a given range rose by a factor of 10 in the 19 years from Explorer I of 1958 to Voyager of 1977. This improvement was attained through ingenious design based on the sort of penetrating analysis set forth in this book by engineers who took part in a highly detailed and amazingly successful pro gram. Careful observation and analysis have told us much about limitations on the accurate measurement of distance. It is not easy to get busy people to tell others clearly and in detail how they have solved important problems. Joseph H. Yuen and the other contribu tors to this book are to be commended for the time and care they have devoted to explicating one vital aspect of a great adventure of mankind.
Book Synopsis Radio Wave Propagation of Satellite Systems by : Zhenwei Zhao
Download or read book Radio Wave Propagation of Satellite Systems written by Zhenwei Zhao and published by Springer. This book was released on 2024-09-10 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the fundamental theories and prediction methods of radiowave propagation for the design, building, and operation of contemporary satellite systems. The primary objective of this book is to inquire into whether and how it is possible in a democracy to effectively decrease short-sighted policies. Although the commonplace expression “responsibility to future generations” has become firmly established in public and political vocabulary, its operational meaning and practice are not as well understood and have not yet been systematically evaluated. It still has not been successfully translated into viable ethical and theoretical concepts that can guide public policies and action. How can modes of governance and established priorities compatible with the well-being of future generations be created? This book identifies the conditions, and the obstacles, for such future-oriented governance. To meet the needs of diverse satellite applications, the book covers the main factors that affect radiowave propagation, including the clear-air effects, the hydrometeor effects, the ionospheric effects, the earth's surface reflection, and the local environmental effects. To enhance the prediction of radiowave propagation, the book elaborates on the characteristics of radio meteorological and ionospheric environments. It also summarizes research progress on the prediction methods of radio noise and interference coordination for satellite systems. The fade mitigation techniques and the propagation analysis of satellite system design are discussed. Providing a comprehensive summary of common practices and latest advances, the book is intended for researchers and engineers engaged in the study and practice of satellite systems, radio propagation, and its applications.
