I'm using "Fundamentals of Applied Electromagnetics" by Fawwaz T. Ulaby.
It comes with a nice CDROM.
It is thick with vector calculus, but even though I've never had a
rigorous vector calculus course, I found that I could manage the
material quite well. It isn't necessary to have a great deal of
theoretical vector calculus ability to do *applied* EM. You just need
to be able to perform the calculations, which are really not hard at all
if you can do basic diff. and integral calculus well. Even the
derivations are Ok to understand with a mostly applied vector calculus
skill base. I would think that a more theoretical focus on EM would
require a more rigorously developed vector calculus skill base.
So it is a question of what you want. Do you want to do EM research and
cutting edge development that will require you to be able to communicate
new discoveries in mathematical form? Or do you want to understand and
be able to calculate and model basic EM stuff as it bears upon practical
electrical engineering, like designing transformers, antennas, and
In the latter case, this book is excellant. The only thing I wish it
had was an extension of transmission line theory from the phasor
treatment to the S domain, for the ability to model arbitrary exitations
of a transmission line. Also, there is no coverage of resonators.
The other interesting thing about this text is that it covers
transmission lines first, before electrostatics and magnetostatics.
This pedagogical approach is becoming popular these days, as the
transmission line is so immediately relevant to all aspects of
electronic design these days, primarily due to the ubiquity of high
speed logic systems.
Good luck with your learning.
