that's a really interesting question, because it's not like a EM wave 
propagating, where the dielectric constant is what you care about. 
OTOH, I suppose that since EM waves are also photons, there must be some 
sort of propagation constant.  But what's the permittivity of rock at 
the frequency (energy) of a neutrino
