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

Dhiraj Sinha

Description

This book is an introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It begins with a brief background on the origin of the concept of symmetry and its meaning in fields such as architecture, mathematics, and physics. Despite the extensive developments of symmetry in these fields, it has yet to be applied to the context of classical electromagnetism and related engineering applications. This book unravels the beauty and excitement of this area to scientists and engineers.
This second edition builds on the introduction to the concept of symmetries in electromagnetism and explicit symmetry breaking. It will also address some of the recent developments in the field of radiation from magneto-electric materials and ferroelectric materials and correlate 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 latter gaining
importance with the current shift to 5G and related wireless technologies.
