Hello,
I do not know much about the TPU threads or what has been discussed. But I thought I would share some information which may be of use. This stands IF the TPU is an antenna of sorts.
Imagine a metal sphere, as a free space capacity, acting as an antenna. Its surface area (capacity) dictates its coupling to the environment. A 1 volt change in potential in the surrounding environment creates a 1 volt disturbance
in the sphere which is referenced to ground. Now if this sphere were charged to a high voltage, the surrounding field "reaches out" and interacts with the environment to a greater degree. For example, if you have the sphere charged to 64 volts, then take a probe at 2 times the radius, you will find on a 16 volt potential (law of inverse squares). If you double your radius again you will feel 4 volts, and again you will feel 1 volt. you now have a sphere of potential with a radius 8 times larger than the metal sphere, with a potential of 1 volt. If there is a 1 volt change in the environment, per the law of inverse squares the sphere in the center (charged to 64) will feel a 64 volt change. It is as if we have drastically increased the surface area of our antenna, and its ability to couple to the environment.
Lesson to take from this example, a charged object, (either electric or magnetic) couples to the environment better than a non charged item.
How do we create a field, which interacts well with our environment?
One way to do it would be to create a ring circuit.
Imagine a toroidal coil, and treat it as a transmission line, so it is a continuous loop. If we hook a single wire up to any point on it, and excite it at a harmonic of the fundamental, we will set our coil into resonance. The single point excitation will propagate around the coil in two separate directions, one left hand wise of our input point, and one right hand. This is a standard resonant mode in such a coil, two waves propagating in two directions, the summation of which is our standing wave. The problem with this setup is the polarity constantly changes. Above the coil you will have a positive potential, beneath a negative, and these will alternate polarity per your frequency. Also your magnetic field will alternate its direction in the same way.
There is a way however to get the wave to propagate in one direction only around the coil, making it a one way transmission line. The wave will travel circularly around the coil in ONE direction only. This is done through directional coupling, or 1/4 wave interference. Excite the ring circuit at TWO spaces separated by 1/4 wave. All wave components traveling one way will cancel, and all wave components traveling in the opposite direction will double. You now have a unidirectional wave propagating around our toroidal circuit. You can using this method create standing waves which will grow until the physical properties of the coil break down causing destruction. (this would be a parametric approach to excite the coil) This is how "diodes" are made in microwave and RF engineering to get unidirectional wave propagation. These ring circuits were once used in industry to test very high power components, when you did not have access to a very high power, power supply.
If a person were to use a ceramic core, which had either piezoelectric or magnetostrictive properties, we will note that a mechanical resonance will also be set up in the core of our toroid. If we can match the frequency of the transmission line to the acoustic mechanical resonant frequency of the core we would be playing with a very interesting device. We are causing a unidirectional spinning field around a toroid, with an accompanied acoustic unidirectional wave. Gyroscopic effects may apply.
