I would like to analyse the effects of passing a laser/microwave through the Earth's atmosphere, in relation to space-based solar power. As I can't do my experiment on the real scale. I would like to know if it's possible to scale it down. I.e. replicating the relative amounts of gas at specific pressure levels in some container, to produce the diffraction effects that would occur from transmitting mw/laser from space to ground. Does Rayleigh-scattering come into play? Or just diffraction. Any ideas, how could I do it for my experiment?
