Classical electrodynamics by J.D.Jackson (encyclopedic)

Classical theory of fields by L. Landau and E.M.Lifshitz (elegant, high brow)

Introduction to electrodynamics by D.J.Griffths (undergraduate but, if you know everything in it, you'll do just fine)

The Classical Theory of Fields by L.Landau and E.M.Lifshitz (high brow, elegant; written by masters and it shows)

Principles of Electrodynamics by Melvin Schwartz (elegant, short)

. . . (there are E&M books for all tastes in the library)

**Time and place: **Mondays
and Wednesday, 2:00pm to 3:40pm

**General remarks:**
Contrary to many other
departments, we have only one semester of graduate E&M in
Maryland.
This is due, in part, to the fact that the mahematical theory of
boundary value problems was already covered in the Mathematical Methods
class. Consequently, we will concentrate on conceptual issues,
electromagnetic waves and radiation. Static problems will be discussed,
but briefly. The other peculiarity of our class is the stress we will
put on some methods (lagrangian formalism, 4 dimensional tensors, ...)
that, besides usefull to understand E&M, will be
particularly
usefull in more advances classes. We will not closely follow
any
textbook though.

Notes

Many typos/mistakes are known in these notes ! They are not a substitute for textbooks.

**Interesting links:**

Prof. K. MacDonald has a large set of lecture notes, problems, pedagogical articles and links on classical electromagnetism here.

This undergraduate lecture notes set by by Prof. M. Peskin constains some material not usually covered in e&m classes like ours (coherence and holograms, Yang-Mills, rainbows, ...)
