@ShellHere is one of the very first simulations I posted. Remember when all we had to go on were the dimensions we could extract from the photo images in the "Anomalous" paper? This is that cavity on start-up excited by a drummed up source. It was showing the start-up of the frustum from power on, probably the first 32 cycles of a run. November 2014.Steve

If you don't mind SeeShells, would you (or anyone else), be willing to give a short explanation as to what has gone on regarding revelations with the antenna? I've been away from the forums for quite some time and am quite interested in this.Thanks!You could start by reviewing the work done by monomorphic on this site using FEKO where he has posted dozens of videos on youtube with not only different geometries of frustums but different antennas. Aero also did dozens of simulations using MEEP that are posted here over the last few years although they are harder to find as the search function on the NSF site isn't the best. Oh, we also did designs of frustums driven by waveguides.https://www.youtube.com/user/monomorph1/videos?shelf_id=1&view=0&sort=ddWhat we did find out is exciting a TE012 or TE013 required a loop to couple into the fields. First attachment. This also can be a modified loop like the one Eugene Samsonov did in his tests in the second attachment. http://vixra.org/pdf/1603.0153v1.pdf While he didn't see any thrusts I liked his antenna design for coupling in a TE012 in the endplate. Eagleworks did thier report with a TM212 and a TE012 mode http://libertariannews.org//wp-content//uploads//2014//07//AnomalousThrustProductionFromanRFTestDevice-BradyEtAl.pdf. My Best,Shell

It looks like a 1/4 Wl dipole positioned in the center, between the endplates. Do you remember what fields were being shown in the simulation?My Very Best,Shell
Guys,So how much funding can I raise when I demo a P-P thruster on a rotary test rig doing at least 20 revs with constant acceleration?Time to get our asses off this rock.Phil

The proof, as always, is in the pudding!

Evidence has been there since 2002.Yet all ignored, including the Yang, SPR & EW peer reviewed papers.Now NASA funds Woodward because Dr. White only delivered a few snow flakes of force using a thruster design that operated well below cutoff.Was lucky to deliver even that amount of thrust plus the torsion pendulum did not allow significant acceleration capability. At least Jamie's design allows significant acceleration distance.

I agree. However, giving heated debates in the past between TT on one side and fierce opposition on the other - like Mr. Members and Dr. Rodal (I respect them of course too). I am not sure this will be a neutral scientific debate.
P.S. On the other side, when addressing concerns of someone’s experiment, it is very important to use as measured a voice as possible. Realize, no matter your intent, you are attacking someone’s work, their time, their energy, their thoughts, in some cases their very soul (at least I am sure it feels that way). Try really, really hard to recognize that fact, and go out of your way to BE KIND!
The Windfreak SynthNV signal source/power detector + directional coupler to measure reflection ('S11')I found the SynthNV (is anyone else but Jamie using it?) to be reasonable useful in finding the narrow resonances of microwave cavities in the range we are interested in. But... you have to scan rather narrow bands. Since the resonance line widths are of the order of 100-300 kHz, and the number of points you can choose in the network analyzer option has a maximum of 1000 (why so low? Is there a way to increase this?), you have to scan bands of 20 MHz or smaller. With sweep of 2-3 GHz you see nothing.
