Doug,

Thanks for the reference.
Reg the bend, I did not understand your statement that
"A change in direction can also be considered "acceleration" with
vectors".
How do you explain this? Did you use "acceleration" in the d by dt of
velocity sense?

Yes and no. The Laplacian/Maxwell derivation which
results in accelerated charge being the mechanism for
radiation is spelled out in a great little book:

Title: "An Introduction to Electromagnetic Wave
Propagation & Antennas"
Author: Shane Cloude
Date: 1995
Publisher: Springer-Verlag New York Inc.
ISBN: 0-387-91501-X
Softcover.

Specifically starting on page 28 and ending on page 30.

The extrapolation from his derivation to a bend in a trace
is mine. Vectors as you're probably well aware are
determined by direction and speed. A change in direction
can also be considered "acceleration" with vectors.
