Very interesting. The first thought that came to mind when I saw your design, esp with the golden rule geometry -- is that it could be a more favorable wave guide than the Shawyer truncated cone (EM drive) for the purpose of directed thrust using RF.
Mabye this is where your are headed but if you haven’t done so (and have a very sensitive digital scale), it could be worth the effort looking for any such small effect. NASA would love to see such a finding as they have taken some heat, so to speak, over their EM drive testing. As for power measurement, there is lots of used Bird RF meters and dummy loads out there (EBay) – but it looks like you have already tried that. Jones From: Sean Logan I built, and am experimenting with an EM resonator. Its geometry is based on the shape of a hyperbolic horn, the natural shape of a vortex in water. Please let me know if you have any insight into what is happening inside this structure, when it is excited with RF. My work is documented here: spaz.org/~magi Also, if you know of a simple circuit for measuring RF current, I am all ears. I would like to look for the "dip" in current which occurs when it is excited at its resonant frequency. Thank you, Sean Logan
