“…A recent investigation on the multiple scattering of light by a pair of uniaxial anisotropic spheres (using a Gaussian numerical integration to calculate the BSCs) [68] observed a linear behavior for half-cone angle values 0°≤ α 0 < 90°, nevertheless, erroneously attributed the linearity of the scattering enhancement to ''the effect of two spheres''. It should be emphasized here that the discrepancy between the results presented in [37] and those of [68] for α 0 > 40°results from the approximation used in the calculation of the BSCs (i.e., the ILA), but not the presence of two spheres. This has also been recently and independently confirmed in [69].…”

“…Since the incident Bessel waves constitute a superposition of plane waves propagating over a cone with a half-angle , it is then anticipated that the scattering would be large at   , which corresponds to the forward scattering of the individual n th plane-wave component with half-cone angle  n . For instance, recent investigations in optical scattering of Bessel waves from a sphere revealed a similar behavior [55][56][57][58].…”

-Based on the partial-wave series expansion (PWSE) method in spherical coordinates, a formal analytical solution for the acoustic scattering of a zeroth-order Bessel acoustic beam centered on a rigid fixed (oblate or prolate) spheroid is provided. The unknown scattering coefficients of the spheroid are determined by solving a system of linear equations derived for the Neumann boundary condition. Numerical results for the modulus of the backscattered pressure ( = ) in the near-field and the backscattering form function in the far-field for both prolate and oblate spheroids are presented and discussed, with particular emphasis on the aspect ratio (i.e., the ratio of the major axis over the minor axis of the spheroid), the half-cone angle of the Bessel beam , and the dimensionless frequency. The plots display periodic oscillations (versus the dimensionless frequency) due to the interference of specularly reflected waves in the backscattering direction with circumferential Franz' waves circumnavigating the surface of the spheroid in the surrounding fluid. Moreover, the 3D directivity patterns illustrate the nearand far-field axisymmetric scattering. Investigations in underwater acoustics, particle levitation, scattering, and the detection of submerged elongated objects and other related applications utilizing Bessel waves would benefit from the results of the present study.

The T-matrix method is one of the most versatile and efficient direct computer solvers of the macroscopic Maxwell equations and is widely used for the computation of electromagnetic scattering by single and composite particles, discrete random media, and particles in the vicinity of an interface separating two half-spaces with different refractive indices. This paper is the seventh update to the comprehensive thematic database of peerreviewed T-matrix publications initiated by us in 2004 and includes relevant publications that have appeared since 2013. It also lists a number of earlier publications overlooked previously.
