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.
