Particle radiation thrust is very small you would get the same amount of thrust from a bank of LED (photons), its there but every small, if I was to make a 35KW block of high efficient LEDS I would get more thrust they would and be more efficient
Creating micro waves very very inefficient 50% to 75% at best
