Quantum physics says that energy exists in discrete packets. These packets are defined by the plank constant. A plank constant is the energy in one oscillation (1hz) of rf frequency. You can't have a a fractional frequency. There is no 107.4 hz. The universe won't let you do it. You either have to broadcast on 107hz or 108hz.
When a photon is emitted it gives the atom that is emitting it momentum equal to what that atom would have gained had it shot out a particle with the same mass at the speed of light.
Very interesting report; another anomaly. Newton's laws still intact though. There is a professor in Greece who claims that an open cone made of YBCO superconductor, with a magnet at the apex generates a thrust. If this seems off-topic I apologize and will not mind if this post is expunged. However it is an interesting claim since the thrust measured is in the milliNewtons. This professor has also been able to patent his device. Below is a simple drawing of this device, from his patent.http://etheric.com/nassikas-thruster-light-years-ahead-of-the-dawn-spacecraft-ion-propulsion-system/http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=1&p=1&f=G&l=50&d=PTXT&S1=8952773.PN.&OS=PN/8952773&RS=PN/8952773

Thus no net Force is generated so no need to be concerned as to the source of the Energy.

I look forward to your commentary.All the best,DaveDave, I really like your report - I think this sort of formal documentation is critical to making people fully aware of DIY builders and their contributions to this original research. I particularly like your contribution to the discussion of Q and the introduction of the QR concept. I am still going over the implications of the math - I had missed that Yang and NASA had such wildly different methodologies - I had been focusing too much on the 1-port vs 2-port debate. However, I will be including a QR calculation in any results I obtain. I'm going to look at it a little more tonight but I think this approach will be very significant with wideband RF sources like maggies. Shell - how are you approaching the "Q conundrum"? HermThanks Herm, the Qr concept is akin to a shape factor, i.e. a 30 to 3dB shape factor being 2.5:1 (or whatever) when talking about bandpass filters. I think it has some merit to "force" unification of methodology. <edit> clarification of shape factor example

NSF-1701 Paper Update. With thanks to many, I am releasing my paper a day early. I look forward to your commentary.All the best,Dave
Dave:I read your paper and was very impressed, very well thought out and put together! Congratulations on a successful experiment. I'm curious though, how do you plan on obtaining 100 times the thrust in your next experiment? Our paper should be ready to publish in the next week or so. Unfortunately we will not be able to continue this year and will instead focus on graduating on time, the department won't let us skip Senior Spacecraft Design for an individual project. But an Electrical Engineering student has contacted me and expressed interest in doing an EM Drive experiment as his senior project, so perhaps I'll play advisor this year! Maybe that will lead nicely into a Masters or PhD thesis on the topic

I think it has some merit to "force" unification of methodology. <edit> clarification of shape factor exampleShape factor was exactly where I was going in my late night noodling and then your post caught my eye. I was trying to come up with a way to relate the concept for those who aren't familiar with filters and their behavior. I have always found shape factor to be a challenge to explain to someone who hasn't built or used or quantified filters. However, I really think there is a similarity here (by that I mean two phenomena which present at least a surface or 1st order similarity without a definite or at least defined conceptual link). Consider the relationship of shape factor to the magnitude of overshoot. And just some way after midnight unconstrained thoughts - isn't overshoot a bit reminiscent of evanescent waves. I know I know that's just crazy talk.Herm

Maybe that will lead nicely into a Masters or PhD thesis on the topic Cool!Well, that the 17.5 millilnewton question...I set the goal arbitrarily to try and get the signature as far above the noise as I think possible from my humble home lab. First will be to clean up the mag signal. Second will be to get it tunable. Third will be to design a feedback system to autotune to best return loss. This will be a big challenge. Not trying to try mechanical tuning of the frustum as I'm afraid it could induce mechanical variations, so trying it electrically first.My head hurts just thinking about it.

Even with the low power EW used you can see the difference in heating caused by the modes. When you apply >10x that power the effects are going to increase as well. I'm not sure how well a PLL will be able to offset the thermal deformations you'll see in the copper sheeting. Have you thought about trying to compensate for those hot spots by re-enforcing the end plates with sinks or a heftier plate? Or do you think it's not a issue. Sometimes I think I worry too much and bonded mine onto a ceramic plate. Shell
Forgot to mention a caution Consider FIRE HAZARD if gets to hot!
Brief layman question. Is there any way to remove the magnetron from the device entirely and instead direct its output into the chamber using some sort of insulated conduit? Not sure if that would really help or just complicate things, but curious if it's been considered.Been reading since Thread 3. Fascinating stuff, keep up the great work.

I've got my magnetron away from the frustum. It feeds into a waveguide>coax and down to the frustum into a waveguide>antenna. I'll lose about 3db in each step but that's workable considering I'll keep heat from the magnetron away from the frustum.I remember there were suggestions on using a feed horn into a matched receiver on the frustum, although I'm not that savvy to want to try it, maybe one of the other (Crazy Eddies) DYIers might give it a shot.

ShellShell, not trying to pollute your punchbowl, but even if the mags were 2 feet away via a mesh or solid waveguide they, themselves, will still try to lift...meaning they will transfer this angular force to the waveguides, then the frustum...unless I'm missing something...which is entirely possible, especially when I do yard work
