Antennas & Propagation for Wireless Communications by Simon R. Saunders, ISBN 0470848790
Antennas and propagation are the key factors influencing the robustness and quality of the wireless communication channel. This book introduces the basic concepts and specific applications of antennas and propagation to wireless systems, covering terrestrial and satellite radio systems in both mobile and fixed contexts.
Including: Illustrations of the significance and effect of the wireless propagation channel Overview of the fundamental electromagnetic principles underlying propagation and antennas Basic concepts of antennas and their application to specific wireless systems Propagation measurement, modelling and prediction for fixed links, macrocells, microcells, picocells and megacells Narrowband and wideband channel modelling and the effect of the channel on communication system performance Methods that overcome and transform channel impairments to enhance performance using diversity, adaptive antennas and equalisers Distinctive features include: Examples of real world practical systems of communication system design and operation Extensive worked examples End of chapter questions Topical and relevant information for and about the wireless communication industry
It is a vital source of information for wireless communication engineers as well as for students at postgraduate or senior undergraduate levels.
The Tests of Time: Readings in the Development of Physical Theory by Lisa M. Dolling, ISBN 0691090858
The development of physical theory is one of our greatest intellectual achievements. Its products--the currently prevailing theories of physics, astronomy, and cosmology--have proved themselves to possess intrinsic beauty and to have enormous explanatory and predictive power. This anthology of primary readings chronicles the birth and maturation of five such theories (the heliocentric theory, the electromagnetic field theory, special and general relativity, quantum theory, and the big bang theory) in the words of the scientists who brought them to life. It is the first historical account that captures the rich substance of these theories, each of which represents a fascinating story of the interplay of evidence and insight--and of dialogue among great minds.
Readers sit in with Copernicus, Kepler, and Galileo as they overturn the geocentric universe; observe the genius of Faraday and Maxwell as they "discover" the electromagnetic field; look over Einstein's shoulder as he works out the...

An Introduction to Active Galactic Nuclei by Bradley M. Peterson, ISBN 0521479118
The study of AGN is one of the most dynamic areas of contemporary astronomy, involving one-fifth of all research astronomers. This textbook provides a systematic review of the observed properties of AGN across the entire electromagnetic spectrum, examines the underlying physics, and shows how the brightest AGN--quasars--can be used to probe the farthest reaches of the Universe. This timely textbook is a clear, comprehensive and self-contained introduction to active galactic nuclei (AGN)--for advanced undergraduates and graduate students in astronomy and physics.

Em Modeling of Antennas and RF Components for Wireless Communication Systems
The book focuses on the practical aspects of computational electrodynamics. A short review of electromagnetic field theory and an illustrative introduction to basic concepts of numerical methods provide the mathematical and physical background. The main part the book guides the reader step-by-step through the modelling process: from the initial "what question shall the model answer?," through the setting up of a computer model by creating geometry, boundary conditions, sources, to post processing, validation, and optimization. A number of antenna and filter examples demonstrate the advantages and disadvantages of different numerical methods. So the book provides a realistic view on the capabilities and limits of state-of-the-art 3D-field simulators and on how to apply this knowledge efficiently to EM analysis and designing of RF applications in modern communication systems.

Electromagnetic Optimization by Genetic Algorithms by Yahya Rahmat-Samii, ISBN 0471295450
Authoritative coverage of a revolutionary technique for overcoming problems in electromagnetic design Genetic algorithms are stochastic search procedures modeled on the Darwinian concepts of natural selection and evolution. The machinery of genetic algorithms utilizes an optimization methodology that allows a global search of the cost surface via statistical random processes dictated by the Darwinian evolutionary concept. These easily programmed and readily implemented procedures robustly locate extrema of highly multimodal functions and therefore are particularly well suited to finding solutions to a broad range of electromagnetic optimization problems. Electromagnetic Optimization by Genetic Algorithms is the first book devoted exclusively to the application of genetic algorithms to electromagnetic device design. Compiled by two highly competent and well-respected members of the electromagnetics community, this book describes numerous applications of genetic algorithms to the design and...
