# Off-axis scattering of an ultrasound bessel beam by a sphere

@article{Silva2011OffaxisSO, title={Off-axis scattering of an ultrasound bessel beam by a sphere}, author={G. Silva}, journal={IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control}, year={2011}, volume={58} }

In this paper, the scattering of an ultrasound zero-order Bessel beam by a rigid sphere in the off-axis configuration is studied. The beam is described through the partial wave expansion. The beam-shape coefficients which represent the amplitude of each multipole mode of the partial wave expansion are computed by numerical quadrature. Calculations are presented for both near- and far-field off-axis scattering. The far-field scattering is examined in both Rayleigh and geometrical acoustic limits… Expand
