Abstract

A simplified model is presented describing acoustic scattering from a toroidal gas bubble in a compressible liquid. It is assumed that the volume oscillations of the bubble are small enough that a linear approximation is appropriate, and furthermore, that the bubble is large enough that the dominant loss mechanism is radiation damping. An expression for the scattering cross section for such a bubble is derived, and the results are compared with finite-element calculations of the full fluid-fluid scattering problem.
