Emitting and receiving EMWs

What does the general electromagnetic field look like?
How do we describe sources of EMWs and why are plane waves unrealistic?
What happens when you restrict the physical dimensions of a wave?
What are the modes of a waveguide and how does it “guide” waves?
What is modulation and why is it so important?
How do you form the signal before feeding it into the antenna and how is it decoded afterwards?
Explicit calculations for the simplest case - a dipole antenna.
