D. Berthet and . Astruc-unpublished, Other details on the numerical simulation can be found in Ref. 48. 60 Strictly speaking, the scattered part of the field is defined far from the vortex core. However, the PW method allows the computation of the sound field everywhere, including the nearfield region in the vortex core. In this respect, what we call here scatt s inc includes the near-field interference pattern . It is an important advantage of the PW approach compared to usual Born approximation, and we hope that the reader will not be confused by this slight misuse of term
