Ed Mitchel said that Meyer discussed standing waves. That's all the proof I need to believe that standing waves play a role in his system.
Standing waves are bi phasic. Two waves traveling in opposite directions interfere to produce a sum which is a stationary waveform. John Kanzius sends rf through salt water, then reflects the waves back through the water again, producing a standing wave. His frequency (13.56 MHz) doesn't completely split the water, so the gas only burns, rather than explode.
With my Meyer's injector build, the rf travels through the injector then produces the plasmoid ignition spark. The energy in that spark back couples through the injector, producing a standing wave. This will split the water fast enough that the ignition spark is still there when the fuel gas hits it.
I'm going to spend less time typing and more time building. I'm standing when I build.
