Mathematica notebook print-outs to assist with Electrodynamics instruction at the level of D.J. Griffiths' text, 4th edition (Prentice Hall), and going somewhat above that level.

This is work in progress (March 2015), and the text in the notebooks was not formatted. Eventually, when the collection becomes more complete they will be made more presentable.

Solution in cylindrical coordinates with DSolve (ODE),
and in Cartesians with NDSolve (PDE).

Fig. 9.18 in the book is bad: phase difference between E and B is max. 45 degrees (k>=kappa) and isn't
changing with distance.
