摘要：

This paper presents some theoretical and numerical investigations concerning the fast computation of an exterior wave field to a scatterer by the Beam Propagation Method (BPM). Different models are presented and compared. It appears that the approach is able to correctly model the propagation of the propagative modes of the wave field while inaccuracies still remain for the evanescent and transition modes.
