Well, at least one thing you guys succeeded :
made me go to the library and start reading.

An initial feeling I have is that equations and
formulas (Maxwell's and alike) do [describe]
these phenomena; however they do little to
[explain] their very nature. Hence, I guess
pretty soon I will dive into quantum physics
to look for some answers.

For example, I needed the Special Theory of
Relativity to get myself convinced of the intrinsic
reality(!) of the electric/magnetic field. And
this was tough, since is hard to comprehend
some form of physical existence without the
support of matter.

Cordially,

Nic.

Below is a paragraph - from a known book -
which I have difficulties understanding. Please
somebody explain in more clear terms the
phenomenon.

the context was about dipole antennas,
however the comment has a general nature

"Radiation of electromagnetic waves is created
when the alternating electric and magnetic fields
attempt to collapse back toward the antenna.
However, new fields being created by the next
half cycle push the preceding fields into space,
which is the mechanism of radiation."

- from "The Beginner's Handbook of Amateur
Radio" by Clay Laster, page 260
