Fields And Waves In Electromagnetic Communications

FIELDS AND WAVES IN ELECTROMAGNETIC COMMUNICATIONS A vital resource that comprehensively covers advanced topics in applied electromagnetics for the professional Electromagnetism (EM) is a highly abstract and complex subject that examines how exerting a force on charged particles is affected by the presence and motion of adjacent particles. The interdependence of the time varying electric and magnetic fields—one producing the other, and vice versa—has allowed researchers to consider them as a single coherent entity: the electromagnetic field. Under this umbrella, students can learn about numerous and varied topics, such as wireless propagation, satellite communications, microwave technology, EM techniques, antennas, and optics, among many others. Fields and Waves in Electromagnetic Communications covers advanced topics in applied electromagnetics for the professional by offering a comprehensive textbook that covers the basics of EM to the most advanced topics such as the classical electron theory of matters, the mechanics model and macroscopic model. Specifically, the book provides a welcome all-in-one source on wireless and guided EM that deals in a wide range of subjects: transmission lines, impedance matching techniques, metallic waveguides, resonators, optical waveguides, optical fibres, antennas, antenna arrays, wireless systems, and electromagnetic compatibility (EMC), and more. The content is supported with innovative pedagogy, the most recent reports and working principles of relevant and contemporary technological developments including applications, specialist software tools, laboratory experiments, and innovative design projects. Fields and Waves in Electromagnetic Communications readers will also find: Multiple practical examples, similes and illustrations of interdisciplinary topics related to wireless and guided electromagnetism Explanations of new topics with support of basic theories connected to real-world contexts and associated applications Sets of technology applications that rely on advanced electromagnetism A series of review questions and drills, end-of-chapter problems, and exercises to help enforce what was learned in each chapter Fields and Waves in Electromagnetic Communications is an ideal textbook for graduate students and senior undergraduates studying telecommunication and wireless communication. It is also a useful resource for industry engineers and members of defense services. Moreover, the book is an excellent non-specialist engineering reference able to be used in other disciplines, such as biomedical engineering, mechatronics, computer science, materials engineering, civil and environmental engineering, physics, network engineering, and wireless services.

This comprehensive introduction to classical electromagnetic theory covers the major aspects, including scalar fields, vectors, laws of Ohm, Joule, Coulomb, Faraday, Maxwell's equation, and more. With numerous diagrams and illustrations.

Wireless communications allow high-speed mobile access to a global Internet based on ultra-wideband backbone intercontinental and terrestrial networks. Both of these environments support the carrying of information via electromagnetic waves that are wireless (in free air) or guided through optical fibers. Wireless and Guided Wave Electromagnetics: Fundamentals and Applications explores the fundamental aspects of electromagnetic waves in wireless media and wired guided media. This is an essential subject for engineers and physicists working with communication technologies, mobile networks, and optical communications. This comprehensive book: Builds from the basics to modern topics in electromagnetics for wireless and optical fiber communication Examines wireless radiation and the guiding of optical waves, which are crucial for carrying high-speed information in long-reach optical networking scenarios Explains the physical phenomena and practical aspects of guiding optical waves that may not require detailed electromagnetic solutions Explores applications of electromagnetic waves in optical communication systems and networks based on frequency domain transfer functions in the linear regions, which simplifies the physical complexity of the waves but still allows them to be examined from a system engineering perspective Uses MATLAB® and Simulink® models to simulate and illustrate the electromagnetic fields Includes worked examples, laboratory exercises, and problem sets to test understanding The book’s modular structure makes it suitable for a variety of courses, for self-study, or as a resource for research and development. Throughout, the author emphasizes issues commonly faced by engineers. Going a step beyond traditional electromagnetics textbooks, this book highlights specific uses of electromagnetic waves with a focus on the wireless and optical technologies that are increasingly important for high-speed transmission over very long distances.

The propagation of waves along and across the boundary between two media with different characteristic velocities is much more complicated when the source is on or near the boundary than when it is far away and the incident waves are plane. Examples of waves generated by localized sources near a boundary are the electromagnetic waves from the currents in a dipole on the surface of the earth and the seismic waves from a slip event in a fault in the earth's crust like the San Andreas fault in California. Both involve a type of surface wave that is called a lateral wave in electro magnetics and a head wave in seismology. Since the two are analogous and the latter is more easily visualized, it is conveniently used here to introduce and describe this important type of surface wave using the data of Y. Ben Zion and P. Malin ("San Andreas Fault Zone Head Waves Near Parkfield, CA," Science 251, 1592-1594, 29 March 1991).
