Correction: Capacitor C1 should be in 1000pF range, 100.0-10,000pF, 15-30kV
All pairs of adjacent rings heterodyne in this manner. This image shows only one example.

Log Periodic Golden Ratio Coaxial Waveguide, Part II
This Documentation describes Open Hardware,
and is licensed under the CERN Open Hardware License
The Wave Articulation Matrix is composed of eight concentric cylinders of ferrous metal.
All eight cylinders have equal mass and equal surface area.
1. Let's assemble the next element around the last completed element.
2. Wrap dielectric material around until we have reached the diameter for the next conductor.
3. Wrap a rectangle of ferrous metal to form a cylinder. This unit was assembled using 0.002 inch-thick Stainless Steel foil, available from Grainger. Ensure that the metal forms a solid, conducting cylinder. Here, the metal is taped together with highly conductive carbon tape (the type used to mount samples in an SEM). If there is a gap between the ends of the metal, it will form a Split Ring Resonator (Parallel LC circuit for U.H.F) -- we do not want that.
4. Finish with a layer of dielectric material.
The envelope of the unit is a Hyperbolic Horn.
Method of Operation
The waveguide can be excited either magnetically or dielectrically. The dielectric method is as follows:
In the initial condition, the central conductor (cylinder zero) is connected to a 1000pF capacitor charged to 15-30kV. A flux of dielectric induction radiates out from this central cylinder in all directions. This flux induces a charge distribution in the surrounding cylinders (we shall call these the Parasitic Elements), and appears to pass through them. The flux is zero within these conductor.
When the triode fires, this flux collapses.
We are interested in the waves which are thus formed in the spaces between the Parasitic Elements.
Whether these are TE, TM, TEM, Longitudinal, or Standing Waves, let us hypothesize that their wavelengths are in some way proportional to the circumferences and/or lengths of the Parasitic Elements.
If this is the case, then when the waves of any two adjacent cylinders heterodyne, they will produce waves with wavelengths proportional to the next larger and smaller cylinders. This is because of the Golden Ratio Log Periodic geometry of the unit.

Nice
Looks good, but not sure about your half bridge driver, would be easier to use a half bridge driver chip

Your waveguide is very interesting, have you done any testing you would be willing to share.
If a waveguide such as yours were inserted into a liquid dielectric and froze at full power would it continue to draw or focus energy when the prime mover was removed. -

Your dielectric version is cool but the magnetic version is intriguing are you using concentric coils?
It would seem a magnetic version would have a broader impact because of the compression caused by the magnetic field but this is your build I could be wrong.
Creating a waveguide seems more plausible that just pulsing a coil and hoping for the best.
It will be interesting to see where this goes ,

bashar STA thread
This is so weird to me. I was writing about this same idea, but
on a "cone" shaped coil.
You could wind several coils, each a PHI ratio of each other and
get them to self-oscillate and heterodyne.
I built two such coils on a cone, one at the hydrogen line,
and one a PHI ratio up the cone and a phi ratio frequency higher.
They both self oscillate. The tuning is a bit tricky.
I believe I spaced them too far apart for the transformer-mixing
effect to be most effective.
I have to re-think the geometry ... but
this idea is AWSOME.
100 monkeys indeed.
I had this idea after realizing the
Hubbard coils are phi ratios in order to
create "heterodyned" frequencies. -

Right On
Right on. I believe that if you heterodyne two waves which are Golden Ratio to each other, you create many many sidebands, both higher and lower in frequency, all Golden Ratio to the next and previous in the sequence. Theoretically, you create a infinite number of sidebands.
If I am not mistaken, the Lakowski Multi-Wave Oscillator is a set of Split Ring Resonators which are all Golden Ratio to each other.
There are many structures, many ways to implement this principle. -

I will post data of initial experiments when they are complete. -

algebra
It may then be possible to create other WAM configurations by first writing them as a transformation matrix, and then expressing this matrix as a three dimensional physical structure.
4. Me:
If you look at the WAM sideways, you will see a vortex with its bottom point at infinity. This is precisely the form taken by water when you stir it around to make a vortex.
Lawrence Edwards discusses this type of vortex on pages 164-167 of the above book. -

New Wiring Diagrams
Attached to this post are the updated wiring diagrams.
Here are the notes:
ASSEMBLY NOTES
1. The Wave Articulation Matrix is composed of eight concentric cylinders of ferrous metal, such as iron, steel, or stainless steel.
2. All eight cylinders have equal mass and equal surface area.
3. The cylinders are whole circles -- they are not Split Ring Resonators. If a cylinder is made by rolling up a rectangle of metal foil, then the two meeting edges must be seam-welded, soldered, or connected with conductive glue.
4. The Wave Articulation Matrix can be described as a Log-Periodic structure, as in a "Log Periodic Antenna". The Log Base used here is the Golden Ratio.

FIRING CIRCUIT OPERATION
1. Capacitor C1 is charged through resistor R1 by the High Voltage Supply.
2. Because WAM cylinder zero (the innermost cylinder) is connected to the high voltage side of capacitor C1, and cylinder seven (the outermost cylinder) is held at a low voltage, an Electric Field exists in the space between these two cylinders.
3. When the pulse generator causes the Triode to go into conduction, this Electric Field collapses, producing wave phenomena.
4. The WAM can be thought of as a wave guide. It has been suggested by Eric Dollard that it exists in the form of a Mode Changer. Not all waves will necessarily be TEM waves. It may be instructive to think of longitudinal waves as described by Tesla in his paper "On the Energy Dissipation of the Hertz Resonator", propagating in a vector orthagonal to the surface of the innermost cylinder. It may be most illuminating to conceive of the interference patterns of these waves as Standing Waves in space, like the standing waves on a transmission line when there is an impedance mismatch between source and load.
5. The pulse generator switches the Triode OFF, capacitor C1 charges up again, and the process repeats.
FIRING CIRCUIT NOTES
1. The Spark Gap is merely a safety mechanism. It acts like a blow-off valve. Its purpose is to protect the Triode from being damaged, should an excessively high voltage develop on cylinder zero for some reason. The electrodes of the spark gap should be separated at a distance such that it will not fire during normal operation, but will discharge the voltage on cylinder zero should it exceed the maximum rated plate voltage of the Triode.
2. The bottom of the innermost cylinder (cylinder zero) is connected to capacitor C1. The top of this cylinder is connected to the Triode or Switching Device.
2. Cylinders 1-6 provide the output of the device. They may be tied together electrically.
3. Cylinder seven (the outermost cylinder) is connected to +12V positive bias.
4. The cathode of the Triode is not grounded. It is positively biased at +12V.
5. Capacitor C1 should be a vacuum capacitor, to allow for the most rapid discharge.
6. It is desirable that the Triode or Switching Device switch from OFF to ON as quickly as possible (fast rise time). What we wish to achieve is the sudden, rapid collapse of a strong Electric Field.
7. The Switching Device does not have to be a Triode. Any high voltage, high speed switching device will be appropriate.
8. The WAM can be scaled to any size. However, for practical sizes (for example, lambda = 60 cm) the waves generated will be in the microwave range. Therefore, the length of any connecting wires becomes significant.
9. Values for R1 and C1 should be chosen such that the capacitor's Time Constant allows it to be fully recharged in between discharge pulses.
10. The Pulse Generator can be a square wave generator operating at approximately 1-2 MHz. It is generally recognized that the 1.995-2.000 MHz HAM band is used for Experimental work. These frequencies are available to any operator holding a General Class or higher HAM license.
11. It may be necessarry to insert a non-inductive resistor between the top of cylinder zero, and the plate of the triode, in order to prevent too much plate current from flowing.
