    • I saw all these project views from Tajmar et al..

      Im still wondering;
      Is there a form of "pumping" goin on in the frustrum? Like in a maser where exited atoms collide with photons and produce a another photon that has the same wavelenght and polarisation and phase and fall back to the old state and so forth .

      Im curious about whats happening INSIDE the frustrum and if the same effect (thrust) can be achieved with a tapered solid state maser.

      Hard to answer without a confirmed theory.

      What would be the expected for the thrust of a solid state maser, or why not a gas maser ?

      It seems the energetic efficiency and density is very low compared to a magnetron?

      A solid state maser might not have the same amount of thrust as an conventional microwave, but its very stable and works around 1.45 gigahertz.
      The Purcell factor is also more controllable. The transmitter in the frustrum disturbs the overall effect more or less. (in the new verson of the EMDrive Shawyer incorporated a small guiding antenna in the frustrum, to prevent distorting, so it looks Shawyer tries to pinpoint the waves) A gas maser is also more fragile and works around 24 gigahertz.


      The microwave used in the original EM Drive include the entire SHF band but a whide range of frequenties is much harder to controll and to measure than a solid state maser.
