They indeed called waves in the literature, and they ARE waves but not conventional perpendicular propagation.
The famous PAVE PAWS case is often cited regarding health issues of high-rise pulse trains, but that involved high megawatt emissions. A satellite has very low energy levels once it reaches ground level, so the concern is mitigated. Also, Brillouin oscillations in dispersive media have been analyzed mostly only for material of uniform composition, but organic matter has a wide range of composition, which may break up the effect because penetration depends on resonant absorption of the energy, but the wide range of atomic types will dampen the effect, like trying to propagate sound through a mix of sand, gravel, and rock.
