Geometrical Aspects of Scattering and Physical Effects of Sound.
Abstract
Research is reported in the following areas: (1) High frequency enhancements of the scattering of sound by tilted elastic cylinders in water are analyzed and observed. (2) The interaction of sound with sound mediated by dilute aqueous suspensions was studied using the frequency shift of a resonator. (3) The coupling of oscillating magnetic fields to the quadrupole quasi-flexural and torsional modes of a stainless steel spherical shell in water is investigated. (4) As an extension of the experimental methods developed for item (1), a PVDF sheet source was used to excite elastic responses of a target but now the target is a large spherical shell in a lake. (5) Transmitted ray contributions and a caustic merging transition for penetrable tilted cylinders are studied using an optical analogy.
