This is my last spreadsheet in comparison to the NASA_Comsol calculations using a single formula based on cylindrical coordinates for all the different modes in the plot. I think this is the border using that kind of equations, for more accuracy the method explained by dr.rodal (or FEM/FDM) , using sperical coordinates (or field simulations)is necessary,not the simple sin/cos properties of the cylindrical system.But I think it's not really bad
Dave, Shell, The Traveler & Crew:It's been awhile since I last posted on this forum and sadly I still can't say anything about what is going on in the Eagleworks (EW) Lab other than Dr. White & I continue to work on testing Q-Thrusters and delving into the science behind them, within the constraints of a still VERY limited budget.Paul March, Friendswood, TX
A question - I'm sure that it has been answered here somewhere but I don't remember the details.In which direction does the speed of light accelerate in the EM drive cavity? That is, are the EM waves moving faster as they approach the large end, or the small end of the frustum? I think it must be the large end because that fits with the idea that the waves interact with the QV and drag the virtual particles (EM disturbances in the vacuum) along with them, accelerating them toward the large end. And of course, just as in Paul March's square dance analogy, the virtual particles disappear into the QV before they do anything more than suck momentum from the EM waves of the frustum. On the other hand, I could be confused about the reaction-action-reaction phenomenon. Maybe its a triple dance step.This is really a pretty simple answer to the question of "What is the cause of the thrust?"
Hello,Mine is the perspective of an outsider who has followed EM Drive for a couple years and this forum only recently. I have been considering dialog about lulls in new information from companies and organizations involved in research along with a lack of funding or even commitment to aggressively pursue the technology. It seems the EM Drive has the potential to be extremely disruptive (understatement). If one accepts the technology as legitimate and predictable in line with what is mentioned here and elsewhere then you would rationally have to accept as legitimate the implications of that technology. Projected non-superconducting EM Drive capabilities are considerable enough but if superconducting cavities can be expected to be integrated into systems routinely 30 years from now, air and space platforms (planes and rockets) could be obsolete for many of the uses considered routine now. That is more than a little disruptive.For someone in charge of budgeting, planning and charting a course for any of the organizations this could impact it could give them, and the people routing information to them, pause. If EM Drive is legitimate and its potential is realized how does one justify 20 or 30 year plans and the multi-billion dollar programs to develop the technology needed to execute them if they may be obsolete shortly after they mature? A deliberate and initially skeptical approach can make sense from this perspective. If and when EM Drive's potential is accepted and unlocked it may introduce some risk and hard questions for a number of people and organizations. I'm not suggesting these dynamics are deliberate acts, but more so that they may just be an inherent part of the environment.Just some thoughts from someone outside the aerospace/NASA community, thanks for humoring them.
The reason I’m writing this? If this force engine were to work, every industry you invest in will be turned upside down. Admittedly, this is a very early call. Inventing a time machine would be more dramatic than EmDrive but not a lot more. A force engine would be like inventing fire.
My understanding is: At the big end, the guide wavelength is the shortest and the group velocity / momentum of the EM wave is the highest.All reverse at the small end.This causes a monentum gradient to develope inside the EMDrive with the EM waves moving toward the small end losing momentum and the EM waves moving toward the big end gaining momentum.The EMDrive then obeys Newton 3 and moves toward the small end to balance the momentum increase toward the big end.End plate bounce force is not directly involved in the Shawyer Effect's externally generated Force but the end plate bounce does setup part of the required environment for the effect to happen.Phil

Still, I do not understand fully. If the EM wave bounces back at the end plate, then the momentum generated according to your explanation does not leave the cavity. You cannot ignore the bounce force (momentum transfer from the EM field to the cavity) just by saying that it is not directly involved in the effect. Can you clarify?
That is, the EM field periodically gains and looses momentum, because of its interaction with the frustrum. The trivial expectation would be that the frustrum looses and gains momentum such that the combined momentum remains always conserved. This is not true in this case? Where does the quantum vacuum enter the picture?
