Found it. 1994 paper from a Tesla symposium. Was on my old laptop from 2018. It's 1.434 megs .pdf author by "anonymous Ph.Ds," titled THE "PHILADELPHIA EXPERIMENT" with a 1967 quote from Vannevar Bush. Google doesn't find that. I think it had been on tucks.nl archive, NOT in the Corum section. Maybe it's still there? I'd search for Philadelphia, not Corum, and not Columbi Egg or Stealth. The Corum paper on rotary fields ends at page ?30? (But this below is the same as the Corums' Columbi Egg paper, except with all the many pages of figures and appendices included, pp30-96.)

Idea: once I made a crude test of a "microwave phosphor" that should be able to see RF shadows. Can it see Philadelphia Experiment?

Rotating drum covered with stripes of LEDs, so the drum surface glows red when spinning fast. Now let short dipole rectennas on the drum each connect to many DC buffers which each drive one LED (perhaps forward bias the rectenna diodes with 0.6V thru choke coils, to eliminate any turn-on threshold.) The drum needs only two sliprings to provide power.

Shine CW microwaves on the rotating drum (perhaps 20mm waves, or even shorter.) The "phosphor" is now being lit up by microwaves. Now hold up your hand, inspect the shape of the shadow. Probably shows fraunhoffer diffraction rings. Hold up a short wire, and in one orientation it's invisible, in another it appears as a black disk ~one wavelength in diameter. Heh, add a poly plastic lens, and now you have a microwave-imaging camera. Perhaps also provide orthogonal antennas each with a green LED, so it "sees" both H and V polarized RF as two different colors. Sell it to Frank Oppenheimer's Exploratorium museum.

To such eyes which can see in the RF bands, how would a partially-working Philadelphia Experiment appear? Perhaps a big silver ball that reflects radio, or perhaps a black sphere that absorbs? Supposedly it starts reflecting visible light if the rotary fields are cranked up fast enough. (Perhaps employ relatively slow rotation as supposedly used in the ship experiment, then wobble the fields with a UHF high-watts emitter, perhaps circularly polarized, to "ride upon" the existing huge b-field coming from the two quadrature loop antennas? If nonlinear, the two signals don't sum, but instead the slow one "lifts up" the fast one's amplitude, as a square-law effect.)

OT: Heh, I also found the Corum BL paper from a Tesla symposium. Many have created Ball Lightning, finding that they're not plasma and not electrical. They are welding-spatter, like a weighty metal aerogel or percolation-structure. They are "fire-balls" as Tesla stated, but a weird form of fire akin to a dense hot aerogel; a low-density blob of fuel-oxidizer, like a nearly solid chunk of acetylene. Disturb it too much, and it goes from slow burning glow to extremely violent explosion. When you have your own pet lightning-ball, don't poke at it, or it gets angry and bites. (But there are more than one form of BL, and perhaps some are combinations of this aerogel welding-spatter stuff, plus added plasma, or at least some high-volt capacitive double-layer effects.)

Hi William, the "missing" Corum rotary-fields paper from 1994 proceedings of
the Tesla Symposium - the url no longer works. Thanks for the Corum
pointers, though, really good stuff. What I'm wondering is, might you have
the missing corum rotary fields paper yourself?
