Principles of electrodynamics

Posted by ubpdqn on February 3, 2012

This is a Dover textbook.  I read this book out of interest as a non-professional. As you can expect, there are pre-requisites, particularly mathematical.  The author gives a concise and sufficient summary of the Mathematics that will be used in the book in the first chapter.

 

This is a bold book. The author confidently dives into derivation of Maxwell’s equations from a relativistic perspective (and the concise, beautiful nature of tensorial representation).  A remarkable feature of the book (to me) was the extent to which important insights can be obtained from simply expressed assumptions and initially static considerations and examples exploiting spherical and cylindrical symmetries.

The author  goes through the necessity of radiation from accelerating charges and the interaction of electromagnetic waves with matter covering: reflection, refraction, refractive index, the Fresnel equations, and diffraction.

Interestingly, the discussion on interference/diffraction did not use Huygen’s principle deliberately. In fact, the author expresses that this approach is flawed. Professor Walter Lewin (author of For the Love of Physics), quotes the book (as a warning regarding the derivation used in his lecture ), in a video lecture on Huygen’s principle.

I enjoyed the author’s writing style. It was clear, concise and passionate. I think students would find this a very useful book with the cost and size advantages of Dover books.
