This completely updated second edition of an Artech House classic provides a thorough introduction to the basic principles of electromagnetic wave propagation of radio frequencies in real-world conditions, fully updated by including new achievements in theory and technology. It serves as an invaluable daily reference for practitioners in the field and as a complete, organized text on the subject. This comprehensive resource covers a wide range of essential topics, from the classification of radio waves, electromagnetic wave theory, and antennas for RF radio links, to the impact of the earth surface on the propagation of ground waves, atmospheric affects in radio wave propagation, and radio wave reception. The book explores the propagation of the ground radio waves, namely the waves that propagate in vicinity of the earth's surface (e.g., guided by that interface), without involvement of any atmospheric effects. Specifics of the high-frequency (HF) radio propagation due to reflections from ionospheric layers is studied, based on commonly used models of the ionospheric vertical profiles. Scattering of the radio waves of UHF and higher frequency bands from the random variations of the tropospheric refraction index (from tiny air turbulences) are also considered by using the principles of statistical radio-physics. Analysis of propagation conditions on real propagation paths, including analysis of the power budget of the VHF/UHF link to assure its stability (percentage of availability within observation time frame), terrestrial, broadcast, mobile, and satellite RF links are presented. The engineering design of the cellular networks, including LTE 4G, 5G and upcoming higher generations is explored. HF propagation predictions for extremely long-range links design for commercial and military applications are explained. Packed with examples and problems, this book provides a theoretical background for astrophysical, aeronomy and geophysical instrumentation design.

Radio propagation is the behavior of radio waves as they travel, or are propagated, from one medium to another, or into different parts of the atmosphere. Radio waves are subject to the influence of the environment in which they are propagated. When a radio wave leaves the boundary of one medium and enters another, the wave changes direction. Radio propagation environments may introduce multipath effects causing fading and channel time dispersion. Various propagation environments have different path loss and multipath effects, leading to the impossibility of radio wave propagation prediction in different propagation environment with the utilization of the same propagation channel model. Understanding the effects of changeable conditions on radio propagation has many practical applications, from selecting frequencies for global shortwave broadcasters, to designing reliable mobile telephone systems, to radio navigation, to operation of radar systems. Radio wave propagation scene portioning plays a very important role in wireless channel modeling. Scene partitioning is also the basis for the upper layer communication network design. Optimization with respect to radio wave propagation will greatly improve the planning of wireless networks for rails. Special railway structures such as cuttings, viaducts, and tunnels have a significant impact on propagation characteristics. Radio Wave Propagation Fundamentals is dedicated to present state of the art reviews and research results delivering information of basic principles commonly used in radio waves propagation. This includes a detailed discussion of different propagation phenomena, including reflection, refraction, scattering, diffraction, ducting and frequency dispersion in different media. Among various subjects, radiowave equations and polarization, transmission media characteristics and its phenomena, K-factor and Earth equivalent radius, and free space and basic transmission losses are included. To understand these topics, good knowledge of fields and waves theory, electromagnetic engineering, antenna theory, and statistics and applied mathematics is required. Also, to get more familiar with the basic principles of radio waves propagation, some examples are presented. This book is valuable for practitioners and students who specialize in antenna, communication and radar systems, providing complete information to the basic principles of electromagnetic wave propagation of radio frequencies in real-world conditions.

This book emerged from teaching a graduate level course in propagation and smart antennas at the Naval Postgraduate School. In its present form, it is suitable not only as a graduate level text, but also as a reference book for industry and research use. The area of radiowave propagation and smart antennas is highly interdisciplinary, extracting material from electromagn- ics, communications, and signal processing. This book is useful to workers in electromagnetics who would like to supplement their background with relevant communicational aspects and to workers in communications who would like to supplement their background with relevant electromagnetic aspects. Anyone with a basic understanding of probability, wave propagation, digital com- nications, and elementary signal processing should be able to appreciate the contents of the book. The book consists of nine chapters with several worked out examples d- persed throughout. Chapter 1 covers the basics of cellular communications. Chapter 2 covers the basic principles of electromagnetic wave propagation relevant to path loss predictions in wireless communications. Students with little prior background in electromagnetics should find the first few sections of Chapter 2 self-sufficient. Empirical path loss models that are used in system design are treated in Chapter 3. The chapter includes the traditional models as well as some of the newer models. Chapter 4 has a thorough discussion on the causes and characterization of small scale fading. The topic of spatial c- relation that is very important for antenna arrays is discussed there in detail.
