About the Book
Principles of Electromagnetics is designed as a text for undergraduate students of electronics and telecommunications engineering. The book contains materials related to static electric field and its behavior in conducting and dielectric medium with boundary conditions, and has wide coverage of topics on energy, potential and capacitance concepts.
The text also explains the topics on magnetostatic, magnetic materials and the behavior of magnetic field at the boundary of different mediums. It also handles the theory related to time varying fields and Maxwell’s equations that help in understanding the concept of electromagnetic wave and power flow analysis using Poynting theorem.
Written in a student-friendly manner, the text includes detailed coverage of fundamentals of electromagnetic field and simplification techniques using vector analysis, differential and integral calculus, which are essential for proper understanding of the subject. Although mathematics is an integral part of the subject, every care has been taken to see that the objective of this book is not lost in the details of mathematical treatment.
