Kapanadze and other FE discussion

[Belfior]

Hi Belfior.
It sounds like you are having a frustrating search finding the G. Kron article.
If you can't find a copy of the article online, you can try going to
a library and see if they can find the article for you. They can check if any libraries
out there have a copy, and can possibly get a copy of the article for you if they can find the
particular publication at a library out there. A university library may be able to help you find it
if a public library can't help you. Give them the following info:
G. Kron, The frustrating search for a geometrical model of electro-dynamic networks.
Tensor (new series), 13, 111 - 128 (1963).

However, Gabriel Kron was by all indications a complete and total propeller head.
Unless you are comfortable with advanced math as applied to complex engineering topics
you may not understand much about what he wrote about in that article, but you never know.
There might be a few interesting tidbits in there that aren't expressed in complex mathematical equations.

Yeah I contacted some sites, that had other The Tensor articles and a university, that has them all. The university has all of them PAST that date, when Kron published his

I would like to learn tensor math and systems analysis, but I also have a life. I just want to read what Kron actually said. The other tidbits in Kron's books are pretty interesting like "Maxwell breaks down if the system is moving" and it seems to mean that you get anomalies, if the coils and other components are rotating

I spoke about efficiency of antennas.

We do not care about Far Field We only care about reactive not radiative region,
look at picture; https://overunity.com/17735/wesleys-kapanadze-and-other-fe-discussion-forum/dlattach/attach/171104/image//

At Schumann resonances (< 30 Hz), the wavelength is > 10,000 Km

Here is  small practical antenna at Schumann bandwidth.

When series circuit is at resonance both reactive components of impedance  Xc and Xl are out of phase 180  cancel each other. the total current will be E=I*R . R never cancels .
( "phase"  is not,  to say it correctly, a property of reactance itself.) the max signal is out at that given  frequency only (+/- width of the bandwidth)
Impedance is the total opposition to AC current.  !!!! I hope it helps you F6FLT to understand it better.
Ohm's Law for impedance as : I = E / Z–Symbolized by the letter Z (in Ohms),
includes both Resistance and Reactance (May be stated as a value and angle, i.e.100/_45o–May be stated as R + jX, i.e. 10 + j20)
Some material for F6FLT to read: https://pdfs.semanticscholar.org/32fb/ebcb46e2420cef0a1c5e373f4ba4c1067b39.pdf

The shortest antenna sizes used in practice are about 1/10 of a wavelength and they are poor. At Schumann resonances (< 30 Hz), the wavelength is > 10,000 Km.

Here you have below  2m long Schumann frequencies  antenna .

ELF antenna...

These antennas have long been made by hams around the world. You can buy an industrial manufactured such antenna.
The output is very, very weak signal, cannot usable as FE/OU.


https://www.aaronia.com/products/antennas/Magnotracker-ELF-6/

Internal Amplifier: 25dB (optional 35dB), battery powered (3-4 hours) or continuosly powered via included power supply

(25 dB - is the first preamp stage.)
Work with such an antenna is possible only with the use of several additional low noise amplifiers with a gain of 10,000 or more. And a very good filter is also needed, otherwise nothing except the background of 50 - 60 Hz can be seen.

Hi there interesting work but must have cost a lot and you must have spent a lot of time building it too.

Can I just show you an attempt I recently made to do some of Wesly's ideas to see if they work for me
I have used one of my collection of Tesla coils  Most of them well all of them tune down to 8hz
one way or another ie 'F' of the coil / by 8 to a whole number no remainder, they all do it. this one I'm showing
here tunes at 1,386,152 Hz / 432 (8 and 9) = 3211
I have yet to rewind the top layer to 90deg  phase shift and retest with my cd4013  phase shift circuit.

Ionized gas or water in a glass, distilled or not, all this is equivalent to thick iron nail for microwave.
My last experiments, a radio transparent box with highly purified, distilled and deionized water 10 mm thick of water, covers the waveguide with microwave 22 GHz 200 milliwatts completely. 200 milliwats without water little warms the skin on the fingers. With the water - absolutely nothing on output is detected by the microwave diode, 1 millivolt. The detector diode D606 (USSR) works up to 50 GHz and above.
Without water - diode rectifies 2 volts.
