Thanks for the nice synopsis.

I would add that, because of how the physics works, the pattern that
evolves doesn't happen during the first cycle, or the first few. It
takes a while, and the more elements involved, the longer it takes.

There were some nice online "movies" (simulations) of an antenna
"building" its near and far field patterns a year or so ago. I will
have to do some googling to find them again, they were quite interesting.
