The underlying principles of the EM druve are very straight forward, easy to understand, and don't violate any laws of physics. The momentum and energy of photons emitted from the antenna (or any antenna) do not exert a reverse force on the antenna or EM drive. All that's occuring is orbial ANGULAR momentum/energy are transferring from the excited atoms in the antenna into generated photons. The exited atom lose energy/momentum as they release photons, the photons ofcourse gain energy/momentum and ultimately transfer it again to a surface on the drive. Photons are not classical and do not "launch" themselves of of an emission surface. (see more detailed response below) No mystery, no quackery, just basic physics.
