Acoustic backscattering form-function of absorbing cylinder targets
Résumé
A new expression of the backscattering form function |f∞(k0a,θ)| for cylindrical targets, suspended in an inviscid fluid in a plane incident sound field, is presented. The theory is modified to include the effects of absorption of shear and compressional waves in viscoelastic materials. The numerical results presented show how damping effect due to ultrasound absorption influences the cylinder’s material properties.
