The donut shape pulses, and you can notice the two halves, which according to Walter Russell do not touch but are forever apart divided by an equator.
Compare it to the pulse of the PULSARS in nature:
The pulsations between cathode- anode and back represents nothing other but a cycle. A cycle according to Walter Russell is " the centripetal journey of a pair of divided units from their zero cathode to its multiplied amplitude, where pairs are united, and the return centrifugal journey to their cathode for rest."
Image above: dying star - This star is returning to its originated cathode for rest. The double dumbbell structure is the typical geometry that indicated this radiation process which represents the end of a cycle. The tip of the junction of those two dumbbell structure would be the place of the anode and the other open sides are the cathodes. In between is usually what is called a field. Fields according to walter Russell
are "areas between waves where the compression of focused light at gravity centers reverses its compression and expands to make the next wave possible.The gradually lowering potential around our earth is a simple example of such a field which surrounds every body in all the universe from microcosm to macrocosm."
The typical shape of a field is like a donut:
