Helix/spiral Antennae transmitter 13.56 mhz

[RF13.56]

I'm trying to get created a helix/spiral Antennae and emprdance match it with the higher RF freq amp.* it has to be able to transmit a RF signal, excuse my language I'm not a tech, but the things I'm interested in is the longitude waves.
I have a RF amp 2000 watt, and I'm into chemistry , so I want to direct the magnetic part as focused as possible into the fluid. Can it be "transfered " in a focused area?.
I have a tech person on the situation, but he is not so much into these smaller helix antennae and all the time he is talking about that he does not understand how to effectively get as much energy over in the fluid as possible. The frequency is 13.56mhz
And I understand the wavelength is approx 22 meters. I understand the problem.
So my question is, can this be done so I get as much if the amps RF "energy"all the way down into my fluid as possible ??
I need the helix/spiral signal
If anybody are willing to give concrete direction ?
Best regar

"Antennas" at this frequency are basically inductors operated at resonance. The magnetic distribution is what you know from spiral inductors, no RF surprises at this frequency.

2kW is a lot of power, given that the inductor is operated at resonance with rather high Q factor.

Question: do you wish to expose the fluid to a magnetic field, or to electromagnetic waves (photons)? There is a difference.

It may be sufficient to immerse the inductor in the fluid. If you make the inductor physically small, then the magnetic field emanates from a small area. However its size puts a limit on the amount of power you can send through it.

By wrapping turns around a metal (or ferrite) core, it concentrates the magnetic field. Only certain metals are suited for this purpose.

To learn how to shoot photons into a focussed area, you'll need advice from someone who has more knowledge than I do.

There are important aspects of utilizing the 13.56 MHz industrial frequency with high power.
The signal is not allowed to be radiated outside the equipment but leakage is tolerated. Therefore no antennas, please.

Depending on the liquid you intend to heat up, the RF heating is possible but I would consider first to use convection heating if possible.
Maybe the liquid is irregular or not homogeneous, then the RF heater would heat up a container or a pipe with that liquid.
I would advise to consult a specialist company handling liquids you intend to process, to design the best method to use. Or run experiments with a lower power level to get important data with which the full-scale system will be designed.

Thanks All.
I can assure you that all will be within what is allowed. I will also be in an University setting.
But this thing when you search the Internet has in my knowledge not been duplicated.
Im really unsure if He uses the Magnetic or the electric field. If he uses the antennae as a curl or
sending and receiving something, but is the wave is 22 meters ???
Here is one of the many links on the internet of what i am trying to understand.
Very thankful for any hints.

I have no idea how they work, but medical NMR (nuclear magnetic resonance) machines produce some very powerful RF fields over a similar range of frequencies focused into a patient.

What you are doing sounds fairly similar.
Some research in that direction may be helpful.

While many youtube scenes are hoaxes, I am not sure what the gentleman actually does with the "saltwater" and RF heating machine.
A salty water is a mixture of H2O and NaCL, possibly other salts. This all does not show me any "fuel" in the resulting steam. That a napkin can burn is OK but not what then burns without it?

Instead of kilowatts indicated in RF heater box you can boil any water mixture much easier on a kitchen range, or in a microwave, with a fraction of power.

If I take saltwater from the Pacific in California, I bet there can be quite nice addition of raw oil. This can generate the flame if the test tube is heated. No high-power RF miracle needed.

As it says in the video, this is probably simply splitting the H2O and burning the hydrogen.
However I would question the practical uses in that you need quite a powerful power source to generate the RF (if that is what is really going on) - you have already mentioned 2kW and where is that power coming from! Are you able to generate more than 2kW form the flame????
Even if this is reproducible in the real world, I would questions its value. There are many other sources of hydrogen for use in hydrogen fuel cells.

Have to agree Susan.

I was once involved on the practical side with a post graduate project that used waste wind generator energy to electrolyse water to generate hydrogen gas as a fuel for cooking.

The idea was sound, because it was waste energy that would otherwise have just been dissipated in a resistor bank. The hydrogen collected over many hours could represent a very worthwhile resource for off grid living.

Anyhow, this water cooled stainless steel tank was filled with lye /water solution (for greatly increased electrical conductivity), and had about 2 to 3Kw going into it. The heat created was ferocious, but it did generate enough gas to make a fairly respectable candle flame.

I watched the above video, and it jogged my memory, and I am thinking that 2Kw of RF power if used directly to heat/burn something, would have to create a much better result than that piddling little flame in the video.

It may have some obscure application, but as a free energy source from seawater it is a big fail IMHO. Its not very much output for 2Kw input.
