Classical Electrodynamics , by J. Schwinger, L.L. DeRaad, K.A. Milton, W-Y. Tsai and J. Norton

This book was written by Schwinger's students based on his lecture notes. It contains a very readable account of some original work on radiation theory that Schwinger did in the 1940s.

This book is not required , and the course will not follow it (or any other text) closely.
