Books on Maxwell's equations in media, boundaries, and waveguides

[Acut]

I am following advice from this page:
http://www.phys.uu.nl/~thooft/theorist.html

and I'm particularly puzzled by the following topics (in bold):

Maxwell's laws in a medium. Boundaries. Solving the equations in:

* vacumm and homogeneous medium (electromagnetic waves)
* in a box (wave guides)
* at boundaries (fraction and reflection)


The vector potential and gauge invariance (extremely important)
emission and absorption on EM waves (antenna)
light scattering against objects.

What books deal with those subjects?
