Thanks for the great answer to what I asked. Then it appears that the energy can go back to the antenna/transmitter. This must have an interesting effect on the antenna Z. I do recall my study of the Poynting vector had to do with the propagated wave and it was easily calculated as a vector cross product, but do not recall that it applies to the near (as I was taught the induced) field. Seems to be the case.
I admit that I am not well read on the literature but what you posted is helpful.
