The often quoted rule: Movement of charge creates electromagnetic radiation.
If you move an electron from here to there it leaves three dimensional
"ripples", not entirely unlike the two dimensional effect of pulling the
point of a stick through the surface of a quiet pool.
There is such a thing as particle radiation with large amounts energy vested
in the velocity and mass of the particle. The most basic concept of
electromagnetic radiation and particle radiation are practically very
different things, though quantum physics ties them together mathematically.
The issues and principles discussed around particle radiation are not
practical for ham antenna design, rather the rule from the first sentence is
the essential basis for transformers and antennas from power frequencies to
way past microwave.
