First of all, it is absolutely incorrect to frame this discussion in 
terms of "power transmission."  The correct term to use is "energy 
transmission."

Here are the wireless energy transmission methods that Tesla investigated:

   1) Radio (electromagnetic radiation)
   2) Earth resonance (disturbed charge of ground and air)
   3) Ground and atmospheric conductivity (includes displacement currents)
   4) Teleforce (macroscopic charged particle beam)
   5) Telegeodynamics (mechanical earth resonance)

The elevated terminals of a Tesla coil RF transmitter and a Tesla 
coil receiving transformer can certainly be multiple wavelengths 
apart if one decides to make them so.

If it turns out that physical reality enters into conflict with the 
mathematical model, clearly the model needs to be adjusted.
