Abstract
The theory of the scattering of plane waves of sound by isotropic
circular cylinders and spheres is extended to take into account the
shear waves which can exist (in addition to compressional waves)
in scatterers of solid material. The results can be expressed in
terms of scattering functions already tabulated. Scattering patterns
computed on the basis of the theory are shown to be in good agreement
with experimental measurements of the distribution-in-angle of sound
scattered in water by metal cylinders. Rapid changes with frequency
in the distribution-in-angle of the scattered sound and in the total
scattered energy are found to occur near frequencies of normal modes
of free vibration of the scattering body.
