Abstract
The scattering of acoustic waves by a finite elastic cylinder immersed in water has been explored theoretically using the T-matrix method. Numerical results were obtained for an aluminum circular cylinder with hemispherical end caps. Cylinders of this type were immersed in water and subjected to detailed acoustic backscattering measurements as a means of verifying the numerical computations. Comparisons between theory and experiment were made at several angles of incidence. The frequency range covered was sufficient to include major, identifiable resonances at each of these angles. In all cases, the numerical results accurately delineated the observed resonances and compared favorably with the off-resonance, backscattered form function.
