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 the extensive developments of the concept 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.
The main audience for the book includes industry specialists and scientists working in the field of antennas and wireless technologies. The book is also highly useful to research scientists working within electromagnetics.
Key Features:
- Presents a brief overview of the concept of symmetries and broken symmetries in different domains of physics
- Highlights the role of broken symmetries in electromagnetic radiation.
- Provides a clear explanation of Gauge Fields in radiation.
- Offers a strong theoretical foundation of radiation from non-metallic systems.
- It holds special importance for antenna designers which is gaining importance against the framework of our current shift to 5G and related wireless technologies
