Electrodynamics-II, Physics 931 (Wysin)
Kansas State University, Spring 2016.
Overview:
The course, part II, is intended for graduate students in physics who have
already completed part I, and who have already had an introductory course in
Electric and Magnetic Fields, or Electrodynamics, at the level of texts like:
Introduction to Electrodynamics, by David J. Griffiths, Prentice-Hall, Inc. (1999);
Classical Theory of Electromagnetism, by Baldassare Di Bartolo, Prentice-Hall (1991).
Electromagnetic Fields and Waves, by Corson and Lorrain, W. H. Freeman and Co. (1970);
Foundations of Electromagnetic Theory, by Reitz and Milford, Addison-Weseley (1967);
The presentation here is at the graduate physics level. The student is expected
to have a fairly good grasp of many of the basic concepts in EM theory. In general,
the implications of Maxwell's equations for the electromagnetic field will be studied,
and applied to the theories of radiation from oscillating or accelerating charges and
currents, scattering of radiation by different media, Einstein's special theory of relativity
and its implications for electrodynamics, and other topics in radiation theory, such as
radiation damping.
Maybe the course could be summarized by giving it an alternative title,
"Electromagnetic Radiation Theory".
In addition to expanding the application of these concepts to more general problems,
a significant part of the course will involve the development of expertise in more
advanced mathematical techniques, including especially the always interesting Green's
functions, generating functions, Bessel functions, Legendre functions, and spherical
harmonics. A solid understanding of how to manipulate these gives you a much stronger
toolbox for confidence in analyzing a wider range of geometries and problems!

Textbooks
The textbook for the course is the world-famous, excellent, but
sometimes hard-for-students-to-read book by J. D. Jackson:
Classical Electrodynamics, Third Edition, by John David Jackson,
John Wiley and Sons, (1998).
This is the book with the blue hardcover, where he changed to SI
(System-International or meter-kilogram-second-ampere) units for the
first 10 chapters. The earlier editions from which I've based my notes
used the simpler CGS (cm-gram-sec) system, where electric and magnetic
fields have the same units. I've tried to incorporate both systems here
where it is possible, however, radiation and scattering theory will
probably be in SI whereas the later topics will follow CGS.
Other Useful Textbooks
Some mathematical help for things like delta-functions, Green functions,
etc., might be found in various Math-Methods textbooks, like:
Mathematical Methods for Physicists, by George B. Arfken and
Hans J. Weber, Academic Press, Fourth Edition (1995).
Mathematics of Classical and Quantum Physics, by Frederick W. Byron
and Robert W. Fuller, Addison-Wesley (1969).
Lecture Notes
Scanned images of my lecture notes. Sometimes there are too many
pages trying to explain the various steps in some simple arguments...
but, you can follow the presentation at the board with these.
