Description

Bogdan and Zweibel have studied the effect on wave propagation of scattering from an ensemble of vertical magnetic flux tubes in a stratified atmosphere, using the WKB approximation. We analyse the effect of an ensemble of general axisymmetric scatterers on acoustic waves in a stratified atmosphere, without using the WKB approximation, and obtain a dispersion relation valid for small filling factors. The properties of this dispersion relation are studied for scattering from density inhomogeneities in a two-layer model atmosphere. It is found that increased stratification tends to decrease the frequency perturbation induced by a population of cylindrical inhomogeneities
