By Jean-Pierre Croisille, Gilles Lebeau
This monograph offers the mathematical description and numerical computation of the high-frequency diffracted wave by means of an immersed elastic wave with common prevalence. The mathematical research is predicated at the particular description of the critical image of the pseudo-differential operator hooked up with the coupled linear challenge elasticity/fluid by means of the wedge interface. This description is therefore used to derive a correct numerical computation of diffraction diagrams for various incoming waves within the fluid, and for various wedge angles. the strategy might be utilized to any challenge of coupled waves by way of a wedge interface. This paintings is of curiosity for any researcher keen on excessive frequency wave scattering, specially mathematicians, acousticians, engineers.
