This is getting fairly esoteric.
Like... If a tree falls in the forest and nobody is there to listen does it
make a sound?
Answer: Yes of course it does.

Yes, that case of an accelerating current would radiate per the acceleration
criteria in 2nd Edition of Kraus. One type of current that would be
accelerating is a simple harmonic oscillation. The harmonic oscillation, like
a sine wave, has changes of direction.
A stationary charge does not radiate he states.
Note the other example, (counter example) a uniform current at constant
velocity in a straight wire, (non oscillating) does not radiate.
In my Kraus, this part of Chapter 2 is section 2-27
Interesting that ed. 3 is so different. I would think something like mine
would be in the first 50 pages or so of your book.
However, I have seen books like the old ARRL Handbooks start right in with wave
theory of the E and H field, and never really say what is the process of
radiation, other than it happens from an antenna.
