Hey Tom, what do you think about Ramo & Whinnery's assertion
in _Fields_and_Waves_... 2nd edition, page 291 " .. we are
often most interested in the ratio of power in the reflected
wave to that in the incident wave, and this ratio is given
by the square of the magnitude of [rho], as can be shown by
considering the Poynting vectors: Pz-/Pz+ = |rho|^2 (3)"

Note the plural "Poynting vectors", Pz- for reflected power
and Pz+ for forward power.

Cecil, concerning Poynting vectors, may I refer you to the last paragraph of
Page 8-3 in Reflections 1, or the last paragraph beginning on Page 8-2 of
Reflections 2.
