Wireless energy transfer experiments ,Builders board

Part 1 of preparation and understanding:

general rules:
1. Zenneck Wave doesn't radiate !!!
but it  radiates...in Near Field before it enters earth air interface at  Brewster Angle.
2. After you  establish proper energy  transfer  into interface it  is not important if it is 1W or 31kW.
3. if you successful in this training from A to B points over the distance  and using this experience you try extracting
energy from Schumann waveguide than amount of energy received doesn't have limit.
but it does
more in my future videos..
4. Zenneck Wave is solution of Maxwell  Equations  and there is not yet  any regulation created in this area
5. if you are able to transfer mW than you  are able to transfer W without any change  to the structure Tx Rx
and than kW and than MW however  at kW/MW Tx is simply more rigid ...that's all.

___________________________________________
Some difficulties to keep Frequency of operation in research of Zenneck Wave
and energy transfer  on a distance  lies in   regulations.
The rule here is the lower is the frequency the better is performance due to lower losses on the signal.
_{Scientific explanation of mentioned  phenomena  is not explained  in this article .}


Frequency of operation for  registered Hams available is
https://en.wikipedia.org/wiki/2200-meter_band

Option  of LF:
-136kHz.=2200m
1/4 Y  wavelength  resonant antenna ~ 1/4 mile  of mile.
But when coiled it is not longer that 6 ft  ( or smaller on 6" former )
Bandwidth: 135.7–137.8 kHz to the Amateur Service on Friday 9 November 2007.
Max ERP power 1W.
Effective radiated power (ERP),- https://en.wikipedia.org/wiki/Effective_radiated_power
Band planThe 2005 IARU Region 1 Conference defined the band as follows:^[3]
135.7–136.0 kHzStation
Tests and transatlantic reception window136.0–137.4 kHz
Telegraphy137.4–137.6 kHz
Non-Telegraphy digital modes137.6–137.8 kHz
Very slow telegraphy centred on 137.7 kHz

I have 2 of Cober 606 ..a much better  option is probably  Velonex 360
Make sure that you have proper plugins ( internal generator or BNC for external  generator)
that weight around 80kg  both operates at  similar  31kW from 10kHz to 1MHz
special license is only required if energy is radiated .But there is no license to have it and use it on proper load  e.g dummy load.
another story is if there is commercial or  research or university entity that has  suitable credentials issued by FCC.
_________________________________

however there is another band that doesn't require license and that is :
https://www.worldwidedx.com/threads/170khz.149673/
But FCC regulation must apply.
HOWEVER ALL OF FCC REGULATIONS APPLES TO RADIATED _{(electromagnetic  wave}) ENERGY INTO AIR  AND ZENNECK WAVE IS NON RADIATING WAVE IN FAR FIELD

receiver :
E.G Late 1940's Hallicrafters steel cabinet AM-FM broadcast band only receiver, covers

Shortwave-Radio/401909474752?hash=item5d93abe5c0:g:R6kAAOSwnSJdlb~F
but  for tests  of low power there are other indicators so receiver is not needed .


Surprisingly to some of you  this is also schematic of Tesla Amplifying coil.!!!!!!!!!!!!!!!!!!!!
And this is simplified schematic of working device for energy transfer
from A to B .
Tx and Rx are exactly the same with the difference that  at the top of the coil there is not an antenna but top capacitor whose regulated elevation
is used for tuning.

 31kW generator for Tx
However Velonex 360 may be much better

Cober 606 high power pulse generator with P-27 low-level pulser.
Functionally equivalent to the Velonex 360.
The Cober 606 is a versatile,
High- Power Pulse Generator that produces a broad range of excellent wave shape
pulses at peak powers of up to 31 Kw.
Very fast rise and fall times, high repetition rates, and a wide range of pulse widths are obtainable.
The unit is capable of operation over the full range and at either negative or positive polarities
without the use of costly plug-ins.
The above and many additional features make the
Cober 606 a most flexible and useful high-power pulse generator .
The 606 is complete with a pulser module for selecting
the pulse width and rep rate, or the user may inject his own
10-volt external pulse. In fact, the 606 may be provided without the
pulser module for those who desire to use their standard low-level laboratory units.
The output from the 606 is continuously adjustable from 0 to 2,500 volts
at an output current of 12.5 amperes. The output voltage is read directly
on a front panel meter, and a 1000:1 capacitance divider allows scope
monitoring of the output wave shape.
The pulse width is variable from 50 nanoseconds to 10 milliseconds,
and the repetition rate is adjustable from a single shot to 1 MHz.
Rise time is adjustable upwards from 20 nanoseconds.
"Floating Deck" circuitry allows 5 KV D. C. isolation of the pulse
from ground and permits either positive or negative pulse polarities,
as selected by the operator. No accessories are required for up to 5 KV D.C.
isolation or pulse polarity reversal. Pulse transformers are available in the event higher
D.C. isolation is desired or for other voltage and current combinations.
Overload circuits, zero start interlocks, and fusing are some of the
safety features that provide full protection to equipment, load and personnel.
testing. Specific applications include use as a power source for
solid-state devices such as Gunn diodes, solid-state lasers and electro-optical
modulators; driving source for gridded and cathode pulsed power tubes, particularly microwave tubes.
The 606 is used for performing destructive or nondestructive testing of
electrical and electronic components and for determining their electrical and life characteristics.
The high voltage and power of the 606 makes it ideal for pulsing gas lasers, plasma tubes and
gas discharge devices.
The high rep rate capability of the 606 makes it especially useful for applications where pulse coding
is desired — bursts with pulse-to-pulse spacing of less than 1 microsecond are available.
The 606 also finds application in the pulse testing of magnetic components as well of other applications.

Dave  you have  rights  to express  your opinion.
I think that  Dave manifests  problem with  basic fundamental  knowledge  about physics of electromagnetic wave.
Here  in this part of forum we ask  you  Dave for link/support/prove/or evidence of your statement if there  is any.
When accepted and known laws of physics  and its models are questioned by anyone it is  nothing wrong with challenging such individuals.
We want the space of this forum to be  condensed to   maximum with  valuable and useful  data.

Sorry I missed this one if you look in The old Sciantists vids he demonstrates this with a radio set up inside to tin box's

I didn't find  this particular  video  of TheOldScientist   however I do remember it
The whole story about Faraday  cage :
In the video
Faraday Cage https://www.youtube.com/watch?v=QU0fLnucE6A
We see that nothing  effects  object inside of it.
However spectrum of spark  is in its maximum of ~1GHz
and electromagnetic field around is measured by electrostatic charge accumulated  on the object.
_____________________________________________
In another video we have exactly the same problem  that was mentioned by The Old Scientist.
The Difference Between Grounded and Ungrounded Faraday Cages Regarding AM, FM & 2.4 GHz WiFi
https://www.youtube.com/watch?v=aWGm8kmoK6A

Faraday Cage - Chicken Wire vs Aluminum Foilhttps://www.youtube.com/watch?v=9M6h1U9jgWs
In this video you see the  difference between chicken wire cage and  aluminum  foil cage.

some explanation: 
-If the size of grid made from Chicken Wire  is higher than  wavelength of the signal than  that wave can penetrate inside of the chicken wire  Faraday box.
-if the size of chicken wire grid  is  lower than only part of that energy is attenuated  and that also depends from polarization of the wave.
_____________________________________________________
now lets go to  full aluminum Faraday box and here we have few surprises.
Instead of  Faraday aluminum box   always  shielding any frequency we may see that  e.g cellphones at 2.4Ghz works there
At some instances we may  also see that FM at 93 MHz is also working but attenuated to some level.
So what is going on?
I hope someone will provide  the answer to it before I come up with it.
