I have worked on the (self-inspired) problem of Meissner Effect being caused by an extra-maxwellian E-field. The outcome is this:
Force of thruster=ExB omega (per volume)
To get a net force, the electromagnetic radiation would have to go through the super-conductor in one direction. So the magnetic field of the radiation should exceed the critical B-field. Note that the non-zero AC resistance of the super-conductor is used, otherwise there will be no electric field inside. The E-field is the E-field inside the super-conductor due to non-zero resistance to AC.
Multiple problems with what you are talking about:
-Good conductors (including and especially superconductors) don't support E-fields inside of them past a penetration depth.
-If you increase the magnetic field past the critical magnetic field, then the material stops acting as a super conductor
-The previous bullet point should be obvious, because if you have a magnetic field in the superconductor (past the minimal penetration depth) then the material does not exhibit the Meissner effect.
-The E cross B that you came up with is simply the Poynting vector, which describes the momentum and energy in fields in general, and just corresponds to a photon rocket in terms of thrust.
You have created multiple thread trying to find loopholes in the laws of electrodynamics, often using superconductors to do so. It is clear from these that you don't really know what you are talking about, and scientists who actually understand electrodynamics have shown that the theory is completely conservative, there is no magic thrusters possible in it no matter what materials you use.
I believe I have asked this before, but what is your goal with these threads? As I just stated, if your goal is to find some kind of better than photon rocket thruster, you are wasting your time barking up the wrong tree. If you want to understand electromagnetism better, there are much more effective ways than repeatedly making flawed claims.
In my model, the Meissner effect occurs only in the moment of transition between normal and Meissner state. After this, the super-conductor acts as a zero resistance gas. It is like a magnetic monopole current proportional to the external B-field and to the speed at which the super-conductive area grows. At the edge, the magnetic monopole current is "closed" to avoid violating Maxwell's Equations outside the volume.

Your statements here make no sense. there is no "moment of transition" from normal to Meissner state. The only transition is between superconducting and non-superconducting. When superconducting, a material has no magnetic field inside of it. You can add and remove external fields continuously and at any rate you choose, and the superconductor continually adjusts to continue excluding the magnetic field (as long as you don't exceed the critical field.)
It does not appear you actually read my previous post, and you certainly didn't respond to my question.
