Did you get to 45.5MHz ?

Hi Verpies. Yes, I viewed the whole spectrum right up to about 112 MHz, and zoomed into various frequency bands
to take a closer look. I have attached some photos showing the yoke core in the aluminum foil shoe box,
and some scope screen shots of the broad frequency spectrum up to 112 MHz.

The blue trace is the time domain trace and the green trace is the frequency domain trace.

I was getting some peaks right at 50 MHz and 100 MHz with the white noise signal off.
Not sure what they are. Could be coming from the scope itself. There are also a lot of other
peaks above 90 MHz, and lots of peaks at lower frequencies with the white noise signal off.
There was one very big peak at 10 MHz, which might well be radio station WWV. Even with the aluminum
foil covered shoebox lid on, it did not noticeably reduce pickup of radio signals and EM noise at all.
Maybe the radio signals and EM noise were coupling right into the scope or scope probe lead itself.

I am just using the spectrum analyzer feature of my scope which is not that sophisticated,
but by zooming into various sections of the spectrum I was able to take a closer look for any
peaks that were not there when the white noise signal was off. I have so many peaks from
radio stations in the low MHz and kHz range that they could have possibly been masking something
underneath.

***************
Edit:
Hmm, I think I just figured out how to work around the problem of picking up all the radio stations
and some of the external EM noise. It appears the radio stations were coupling into the coil from
the chassis ground of the signal generator. If I only connect the red lead from the signal generator to one
side of the coil and leave the signal generator chassis ground connection only connected to the scope probe
ground clip, it seems to be looking much better. I am also seeing an interesting peak when I turn on the white noise, but it is
possible my signal generator's 'white noise' signal may be producing this peak. I will need to test further,
and I will report the results back here later...

Hi Verpies. Ok, I think I have the problem with radio signals coupling strongly into the core winding solved now.
I have to leave the signal generator chassis ground lead unconnected to the coil. If I only connect
the signal generator red lead to the coil, the radio signals and some of the other noise is gone now.

The first screen shot is showing the frequency spectrum up to 5.6 MHz with the sig gen's white noise
signal connected directly to the scope probe without any connection to the yoke core. There are no peaks
in that frequency range.

The second screen shot shows the same 0 to 5.6 MHz frequency range with the signal generator feeding
one side of the 50 turn coil (my test coil is actually a little bit less turns than that). I get a big peak
around 2.89 MHz, but I tested and it is definitely the resonant frequency on my 46 turns or so winding.
As I place my hand closer and closer to the winding, I can see its resonant frequency slowly drop in relation
to how close my hand is to the coil. That peak is not coming from the core at all. I suspect that they were
probably also seeing a winding resonance at around 1.x MHz in the Lithuania experiment, similar to the winding resonance
I am seeing. When I read the procedure they followed, I am inclined to think that they were just working with
coil resonances. I really have my doubts about any of this having anything to do with NMR. (By the way,
with my new improved method of viewing the frequency spectrum from the core, I also see no peaks at 45.5 MHz).

The setup that they used with the yoke core in the Lithuania experiment appears to be very similar to what Akula
has show in his own high power devices, except Akula didn't do it all on the yoke core itself, but it appears to me
that what he did is a very similar approach except using some external air core coils instead for mixing the waveforms.
That is my opinion at the current time anyway. :)

It's good that you got rid of the radio inference.  I am not sure that this groundless method does not introduce artifacts of its own.

With incomplete magnetic circuit and small voltages that you are applying you are not modulating the magnetic permeability of that ferrite core electrically, as described in that IEEE paper.
Also, without a perpendicular DC field and considerable currents, you don't stand a chance to evoke NMR or NAR.

If your material is the same as the STAAR team's, then these ferrite resonances exist even if they are currently obscured by the much stronger LC resonances, but you can still identify them, by deliberately varying the C, in order to cause a shift in the LC resonance frequency and noticing which spectrogram peaks do not move sideways as the C is varied.  Their amplitude will still vary with C, though.

Hi Verpies. It is exactly for the reason that in the Lithuania experiment they state that they were able to
light the 150W bulb while only driving the core windings with two low power signal generators that, if accurate,
I have my doubts about NMR being a factor. It seems to me for NMR to be potentially much of a factor at all that
you would need to be driving the windings on the core with much stronger waveforms, but I could be wrong
of course. I suppose this could possibly be some other effect that occurs in a ferrite core such as 'spin waves'
or some other effect.

I guess I should probably take a closer look at the smaller peak that appeared at a lower frequency than the
large resonant peak from the winding, as circled in the attached screenshot. I will take a closer look at this
as soon as I get the chance, hopefully later on tonight. It may well just be due to a smaller magnitude resonance
in the winding, but I have a idea on how to check further into this. Will report back later...

After identifying the frequency to which material responds the LC frequency is matched with it by changing capacitor value so everything ends up on single frequency.
The main trick there is about 90 degrees angle between windings and the copper strip. While you use 15 and then 50 turns coils for the signal input the resonant frequency reveals best response on the copper strip (with no capacitor attached).
Also there is noticeable level when the minimum core magnetization level is reached. The signal changes rapidly after the minimum barrier is reached.
