Mike was responding to Cecil`s question:
"Does energy per unit time propagate?"

Of course it does. Energy at point A flows to point B where it does
work. The rate at which energy flows is power.

My ultimate authority for radio and electronics is Terman, and his 4th
edition of "Radio and Electronic Engineering" published in 1955. It is
my technical bible. On page 904 Terman discusses the Sommerfeld analysis
of ground-wave propagation. Terman says:

"The field strength at unit distance in Eq. (22-1) depends on power
radiated by the transmitting antenna, and the directivity of the antenna
in the vertical and horizontal planes."

The IEEE dictionary won`t dispute Terman. If it does, it needs
correction.
