Kapanadze and other FE discussion

What made you choose the size of your secondary, working with 160 meter amateur radio ?

It wasn't me but Dr. Corum who started from 144 MHz going down to 50 MHz going down to 1.8 MHz due to his license privileges,
in early stage of  his scientific investigation, of energy transfer from  A to B using surface wave.
Surface wave,  is generalization that includes all of the waves mentioned here including Zenneck Wave
https://youtu.be/wIIABIU3tRw?t=27
Despite its frequency it is the same phenomena , deferring mostly with  methods  of excitation.   
it is in your own interests to view all videos from  that channel:
https://www.youtube.com/channel/UCPC6uCfBVSK71MnPPcp8AGA

The core of everything is  in almost never mentioned by me evanescent wave
https://en.wikipedia.org/wiki/Evanescent_field
But it is a very foundation, for educated researcher to understand this:
http://rexresearch.com/corumzenneck/texzon.pdf
-that excites a pure Zenneck
surface wave with  no radiation field.
1.8 MHz 160 m was just convenient for Dr. James Corum to his publish results
he could use 135.7kilohertz – 137.8kilohertz with 1 W EIRP maximum
before he got the license for 125 kHz https://fcc.report/ELS/Viziv-Technologies-LLC

So there are two factors,
– What Frequency you use for experiment
   and
– What frequency you publish that you used for your experiment ( legal reasons)
My suggestion is for you to deep your knowledge about evanescent waves
and its properties.

For average audience some history:
https://www.evangel.edu/press_releases/tesla-wireless-electricity-corum/
Something more or less important about evanescent waves:

This phenomenon, known as the evanescent wave, extends only to a short distance from the interface,
with power dropping exponentially with distance.

https://www.sciencedirect.com/topics/chemistry/evanescent-wave

-but it is exactly matching to the explanation of Zenneck wave in the interface.

The missing part in that quote is that  evanescent wave is seen as  separate  phenomena by itself,
and Complex Brewster Angle is not taken into consideration.
while  the word: Complex  makes all the difference to  the traditional understanding of Brewster angle

What is your understanding of the low loss inside the waveguide, normal waveguides have much higher losses than the Corum's claim ?

omnidirectional propagation in free space free_space. is restricted by inverse square law Inverse-square_law#:~
impedance of free space is Z₀ = 376.7 Ohm.Free-space path loss is: FSPL = ` ((4 pi * d*f)/c)^2`
and it is based on frequency https://en.wikipedia.org/wiki/Free-space_path_loss

generalizing we may say:
The lower is a frequency the lower is the loss over the distance.
however inverse square law doesn't apply to waveguides!!!!!!


experimental analysis shows signal strength of 1W to 86% between New York and Los Angeles in the interface. at 17kHz
Note: it is not a power but percentage of the efficiency factor that is important for us to look at.

general rule:
The closer we are to Schumann frequency, the lower is our loss per unit of distance in the interface _{(2D waveguide)}
____________________________
That also applies to extraction of energy from Schumann waveguide.

Maybe there is something(energy) in this waveguide, as you say at a frequency of 17 kHz.
But the mistake is that you are trying to extract it (make a connection) in the traditional
ways for radio engineering. And at such low frequencies it does not work well.
It works well at high frequencies.

about the losses versus frequency .

in free space point source propagation differs from line source
https://www.youtube.com/watch?v=MmenXrCt8L4
https://youtu.be/ZoOvABpLvzI?t=58
point source produces spherical wave
Line source produces cylindrical wave
Example: vertical dipole.
https://www.sarthaks.com/223896/a-line-source-emits-a-cylindrical-expanding-wave-assuming-the-medium-absorbs-no-energy

In  Dr. Corum technology we  are dealing with cylindrical wave
and that is why Tesla coil must be vertical in regards to the interface, while electric and magnetic fields are perpendicular to the direction of propagation.

No worries Wesley,

I was only responding to something you wrote or said re Corum, cant recall.

Anyways odd diameter for that coil former, looks like PVC but not familiar with the size unless it's been turned down.

Have some optics background so have mentioned evanescent multiple times on this thread in relation to this device.  Really nice presentation when the guy pours the glycol with the laser illumination.

Certain kinds of mirrors treat photons as displacement current.  https://opg.optica.org/josaa/viewmedia.cfm?uri=josaa-2-9-1429
