Would absorbing photons make the EmDrive more efficient?


The EmDrive (fig. 1) is supposed to work by bouncing microwaves (photons) back and forward. Due to the shape of the thruster the photons will hit the left side at a higher speed than the right side.

This would create a large force on the left side of the thruster and a small force on the right side.

I wonder if it would be more deficient if the microwaves (photons) would be absorbed by a black surface (fig. 2). There would be no need to hit the right side and result in a smoother acceleration.

If so, what kind material would be first choice for the photon absorber and would cooling the photon absorber be difficult or even counter-productive for generating trust?
