Updated Maxwell's equations and added boundary conditions.

Looks great to me!

Just two little things which I found (see below), could you have a look if I'm right?

Besides that, people start asking about anisotropic permittivities.
We can probably include them directly by just writing $\varepsilon$ and $\mu$ as $\boldsymbol{\varepsilon}$ and $\boldsymbol{\mu}$, right?
(seems like mathbf doesn't work for them but boldsymbol works fine.

Corrected another typo and changes arguments -> dependencies

If we consider anisotropic material, we need to change eps and mu into tensors, not vectors. I think it will not help here, but could be a side comment for future references.
btw. for plasmonic problems (metals), we should also not drop the time dependence, so the most general case is keeping everything, though this might not be the most instructive case.
My suggestion would be to leave it for now and extend it later.

Sounds great! I just closed/reopened the PR to run the automatic tests, afterwards I'll merge :)
