It appears that the experiment is a legitimate one.

I think the issue is one of beaming microwave to the thruster in space to drive it. It still requires an external RF source.

This statement in the article puzzles me:

“It works by simply bouncing microwave photons back and forth inside a cone-shaped closed metal cavity.”

To me, microwave RF is not the same particle as photons. This makes me suspect the concept.

All EM waves are composed of photons, but the energy of the photon varies inversely proportional to wavelength (E = hc/λ).

To me, microwave RF is not the same particle as photons.

ANY EM radiation can be expressed either as waves with a specific wavelength or photons with a specific energy.
