Sensitivity of the inverse wave crest problem

In a previous paper [Physica D 141 (3-4) (2000) 316], the inverse problem f or wave crests was introduced and a solution strategy for two-wave interact ions was given. Here these solutions are actually constructed, in particula r for the cases with small interaction angle, moderate phase shifts, and/or symmetric interactions. Two detailed examples are presented and analyzed. The sensitivity of the method is investigated, and conclusions about the pr actical applicability are given. (C) 2001 Elsevier Science B.V.
