This completely revised and expanded edition of an Artech House classic Polarization in Electromagnetic Systems presents the principles of polarization as applied to electromagnetic systems. This edition emphasizes the concepts needed for functional aspects of systems calculations and device evaluation. Readers find up-to-date coverage of applications in wireless communications. The fundamentals of polarization are explained, including the principles of wave polarization along with their mathematical representations. This book explores polarized, partially polarized waves, and unpolarized waves. The second part of the book addresses applications of polarization to practical systems. Antenna ...
This book presents a detailed analytical and computational electromagnetic (CEM) treatment of guided electromagnetic (EM) wave propagation in independently time-varying dielectric medium, using the finite-difference time-domain (FDTD) simulation technique. The contents provide an extensive literature review, explaining the importance of time-varying media (temporal photonic crystals) in new exotic applications that involve rich EM phenomena such as parametric amplification, frequency conversion, non-reciprocal gain, electromagnetic energy accumulation, temporal coating and temporal aiming (beam-forming). A one-dimensional (1D) FDTD simulation paradigm is then formulated in this book, startin...

Written by a leading expert in the field, this practical new resource presents the fundamentals of electromagnetics and antenna technology. This book covers the design, electromagnetic simulation, fabrication, and measurements for various types of antennas, including impedance matching techniques and beamforming for ultrawideband dipoles, monopoles, loops, vector sensors for direction finding, HF curtain arrays, 3D printed nonplanar patch antenna arrays, waveguides for portable radar, reflector antennas, and other antennas. It explores the essentials of phased array antennas and includes detailed derivations of important field equations, and a detailed formulation of the method of moments. T...
'Passionate and moving and provides further evidence of the universality of football' Jonathan Wilson, FourFourTwo The definitive story of the Middle East's unstoppable rise to football superpower, and the road to the Qatar World Cup When James Montague first began covering football in the Middle East two decades ago, people asked him what future there could possibly be for the beautiful game in one of the most volatile regions in the world. In the years that followed, it would become one of the biggest stories in global sport, from the from revolutionary ultras of the Arab Spring and the takeover of some of the world's biggest clubs by the Emirati super rich, to Qatar's controversial journey towards hosting the 2022 World Cup finals. The only Western journalist covering the story on the ground from the very beginning, James Montague tells the definitive tale of the region's rise to ultimate power player in the global game in a fully revised and updated edition. Travelling to every country in the Middle East and meeting fans, players, workers and campaigners, he paints an unforgettable picture of football in a controversial, vibrant and surprising new world.

This text presents papers on compact antennas and their performance characteristics. It covers topics such as: array antennas; reflector and feed antennas; microstrip antennas; adaptive antennas; phased array antennas; integrated antennas; and wire antennas.
Updated with color and gray scale illustrations, a companion website housing supplementary material, and new sections covering recent developments in antenna analysis and design This book introduces the fundamental principles of antenna theory and explains how to apply them to the analysis, design, and measurements of antennas. Due to the variety of methods of analysis and design, and the different antenna structures available, the applications covered in this book are made to some of the most basic and practical antenna configurations. Among these antenna configurations are linear dipoles; loops; arrays; broadband antennas; aperture antennas; horns; microstrip antennas; and reflector antenn...
