Abstract
A method and an apparatus for systematic suppression and separation of interactive acoustic modes within a liquid-filled spherical resonator are described. The method and apparatus allow for augmenting the response and acoustic energy of liquid-filled spherical shell resonators. In some aspects, manipulation of acoustic resonant modes is used to achieve desirable conditions. The response of a system can be influenced by one or more of the interactive modes, which are more sensitive to a change in the speed of sound. This is attained in some cases by changing parameters, which are a function of the speed of sound in a liquid medium, such as, temperature and pressure.
