closed trajectories and electron's clock (de Broglie's, zitterbewegung) performing integer number of ticks during a single closed orbit, like in quantization for Couder's droplets:

@Jarek : That is what R.Mills assumes and describes as phase locked in photons. But the non-radiation condition states that at each "point" (during one phase the integral over the corresponding/ convoluted spherical harmonics should vanish) of the orbit the photon current an the electron current should be (in average) orthogonal.

Just assuming that this also could be the case with highly eccentric orbits, is wish level assumptions. Mills mathematically shows that it works fine under central-fore conditions with certain well defined ratios of a/b axes of ellipsoid trajectories.

I suggest you deliver a proof (mathematical) for these more general assumptions - which would be great!
