Abstract:
Measurements were made of the radiation from individual, small acoustic
sources located close to a submerged, compliantly coated, thin cylindrical shell
in the 1ka>5, the field
is simple, and is well approximated by a source and its negative image. For
ka<4, the pressure field is characterized by significant spatial variations,
owing to contributions from the elastic response of the coated cylinder.
Finite-element model results are compared with the measurements, and are used to
provide insight into the interactions between the source and the coated shell.
