A 180 degree shift for the same signal is interesting when TWO wires are connected.
See that the yellow output amplitude is greater than the input. You will only see this when you match the resistor.
I am not saying anything yet.

Blue - ch2 (right side on video)  + SG

Dzięki za zdjęcia oscyloskopu.
Teraz jest bardzo jasne, co pokazujesz.
Czy pierwszy oscyloskop obrazuje wejście fali kwadratowej, a drugi oscyloskop obrazuje wejście fali sinusoidalnej?
Czy jest jakaś różnica, czy kabel koncentryczny jest cewką czy nie?
Dziękujemy za udostępnienie

Thanks for the oscilloscope pictures.
Now it is very clear what you are showing.
Is the first oscilloscope pictures a square wave input and the second oscilloscope pictures a sine wave input?
Is there a difference if the coaxial cable is a coil or not?
Thank you for sharing

Regards
Luc

1.Is the first oscilloscope pictures a square wave input and the second oscilloscope pictures a sine wave input?
2.Is there a difference if the coaxial cable is a coil or not?

1. YES  (square, sine)
2. no coil.

Title:
Wireless Energy Harvesting by Direct Voltage Multiplication on Lateral Waves From a Suspended Dielectric Layer

Link: https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=8053760


Marconi's early experiments,
ABSTRACT:
This paper explores the feasibility of wireless energy harvesting by direct voltage multiplication on lateral waves.

wireless energy was successfully and safely transmitted and harvested over 2 miles of a hilly area by grounding
and lengthening monopole antenna as a way to reduce
the aperture size of the antenna. Marconi concluded from his first breakthrough experiment that his antenna
radi-ated vertically polarized radio waves that could travel distances much longer than other conventional counter-
parts. Later, he even achieved non-line-of-sight (NLOS) propagation of  wireless  power  across  the  Atlantic

Trapped surface wave is an evanescent wave propagating by successive internal reflections due to an incident electromagnetic wave
striking at an interface with an angle greater than the critical angle

Trapped surface wave is an evanescent wave propagating by successive internal reflections due to an incident
electromag-netic wave striking at an interface with an angle greater than the critical angle.

So that says  that angle can be bigger  than instead  of statement of  Corum Bros  that angle  of  wave tilt in significantly  critical
and must be  exact.  This information   sufficiently  simplifies  our study  and experiments
However  Dr King stays  that:
This lateral wave( another name  for Surface  Wave although some scholars  see  the differences  between the  two)
is a

vertically polarized electromagnetic wave on the top surface of the ground as a result of an incident electromagnetic
wave striking the air-ground interface from below at exactly the critical angle

Interface between two different dielectric media, the critical angle is only applicable to the dielectric medium with a higher refractive index.To excite this lateral wave, it is logical to bury the lower end of transmitting and receiving aerials into the dielectric
layer with a higher refractive index in much the same way as grounding a monopole antenna in Tesla's or Marconi's work [2], [16]–[18].
In fact, the vertically polarized radio wave as referred by Marconi or ground current referred by Nikola Tesla is most likely equivalent to
the lateral wave referred by King, Tamir and many other researchers in the field of wireless energy harvesting.

suspended layer of dielectric material can be modeled as a 4-layered stratified ground with imperfectly conducting ground.
The stratified ground with imperfectly conducting ground can support propagation of both trapped surface waves and lateral waves

The existence of trapped surface waves is possible if and only if the suspended layer of dielectric material is sufficiently thick,
perhaps, thicker than half of the wavelength.
To rule out the possibility of trapped surface waves being present to a significant extent,
we have chosen to study the suspended dielectric layer with a thickness substantially smaller than half of the wavelength.
Examples of this stratified ground with imperfectly conducting bottom plane
include a table top, an iron-reinforced concrete wall or any suspended dielectric layer coated with an oxide.

Conclusions from part#1
Conclusion#1 from part#1
Ground should be layered that  means:
e.g:
-sand
-gravel 
-rock
Conclusion#2 from part#1
- that could  possibly  explain why  in Kazakhstan Akula device works and  not  in Riga Latvia
but
- Ruslan device   works in Riga  Latvia at another  location than Akulas device  in Riga Latvia  and  doesn't  work in Hamburg Germany.


Discription of  the picture below:
_{This dielectric configuration is similar to the 4-layered ground that has already been considered in other studies [14], [20],
with an exception that the bottom layer in the present work is a layer of air with an extremely small conductivity.}
The red line on the picture shows  both :
- the  angle  of wave tilt
-  the surface wave  named as : lateral   wave in the interface.

_{Note:  lateral wave and surface wave are  explained as differing in properties by some   scientists  however  for simplicity,  we 
           omitted  such controversies in regards to this type  of TEM in TM  mode.}
