Sept 2, 2012
Work through the plane wave solution to Maxwell's equation in linear isotropic charge free media without boundary value constraints. I may have attempted to blunder through this before, but believe this to be more clear than any previous attempts. What's missing is relating this to polarization states of different types and relationships to Jones vectors and so forth. Also, it's likely possible to express things in a way that doesn't require taking any real parts provided one uses the pseudoscalar instead of the scalar complex imaginary appropriately.
