Hello Szczepan.
I am a licensed radio amateur and I am concerned with matching my aerial to
my transceiver. I'm personally not at all concerned about any heating
effect, theoretical or actual. Sounds like a topic for one of the physics
newsgroups.
As for textbooks, I have a shelf of them. You'll remember the
recommendations I made in other posts.
Regards, Ian.
