"Electromagnetics is all around us. In simple words, every time we turn a power switch on, every time we press a key on our computer keyboard, or every time we perform a similar action involving an everyday electrical appliance, Electromagnetics comes into action. It is the foundation for the technologies of electrical and computer engineering, spanning the entire electromagnetic spectrum, from direct current to light, from the electrically and magnetically based technologies to the electronics technologies to the photonics technologies. As such, in the context of engineering education, it is fundamental to the study of electrical and computer engineering. While the fundamentals of electromagnetic fields remain the same, the manner in which they are taught may change with the passing of time owing to the requirements of the curricula and shifting emphasis of treatment of the fundamental concepts with the evolution of the technologies of electrical and computer engineering. The present book titled, Advanced Engineering Electromagnetics presents comprehensive coverage on advances and applications in the modern development of electromagnetics. This book covers state of the art research and reviews on new theories, methodologies and computational techniques, and interpretations of both theoretical and experimental results. It provides a thorough treatment of the theory of electrodynamics, mainly from a classical field theoretical point of view, and includes such things as formal electrostatics and magnetostatics and their unification into electrodynamics, the electromagnetic potentials, gauge transformations, covariant formulation of classical electrodynamics, force, momentum and energy of the electromagnetic field, radiation and scattering phenomena, electromagnetic waves and their propagation in vacuum and in media, and covariant Lagrangian/Hamiltonian field theoretical methods for electromagnetic fields, particles and interactions. This book will appeal to engineers and scientists in the electromagnetics profession and will act as a source of new topics for researchers in electromagnetics."
