Explicit Symmetry Breaking in Electrodynamic Systems and Electromagnetic Radiation (Second Edition)

The book aims to unravel some of the nature's mysteries by correlating the nature of fields and the transformations in their symmetries. It begins with a brief background on the foundation of symmetry and its meaning in fields such as architecture, mathematics, and physics. A special focus of the book is on the concept of symmetries in electromagnetism and explicit symmetry breaking which generates radiation. Despite extensive developments of the phenomenon of broken symmetry in different domains of physics, it has yet to be applied within the context of classical electromagnetism and related engineering applications in a broader context. For example, the mechanism of generation of electromagnetic radiation from thin films and non-metallic materials at radio frequencies remains poorly understood and the book offers a lucid exposition to it.

This second edition builds on the introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It addresses some of the recent developments in the field of radiation from magneto-electric materials and ferroelectric materials and correlates them to the nature of symmetries in physical systems. New chapters include coverage of radiation mechanisms from magnetoelectric materials, the role of gauge fields in radiation, and antenna design and symmetries.

The key audience for the book includes Industry specialists and scientists working in the field of antennas and wireless technologies.
