A sketch of the cross section of an AEB. and denote the inner and outer interfaces, and are the distances from the origin to the inner and outer interfaces, respectively.
(Color online) The snapshots of a bubble's oscillation. (a), (b) The maximum compressing and expanding phases during a completed cycle, respectively. The shaded regions denote the bubble's shell whose thickness is enlarged by a factor of 8 for visualization.
(Color online) The evolution of the interfaces at (a) and (b) during two cycles, .
The cross section of the AEB whose surfaces are two unconcentric spheres. The inside and outside spheres' centers are located at and , respectively, with the distance of . and are the radii of the two spheres.
(Color online) The relationship between the sound amplitude and the minimum thickness of the shell. The numbers on the curves denote the eccentric degree. The dashed line shows the critical thickness .
The geometric parameters.
