| Abstract: | Summary. We consider the acoustic scattering of time-harmonic spherical waves from an eccentric non coaxial spheroidal structure simulating
the kidney-stone system. The proposed analysis is based on the application of the translational addition theorem for spheroidal
wave functions. The resulting theoretical model is frequency-independent. Numerical results concerning the applicability of
our approach are also presented.
