By Jean-Pierre Croisille, Gilles Lebeau
This monograph offers the mathematical description and numerical computation of the high-frequency diffracted wave through an immersed elastic wave with basic prevalence. The mathematical research is predicated at the specific description of the primary image of the pseudo-differential operator hooked up with the coupled linear challenge elasticity/fluid through the wedge interface. This description is thus used to derive a correct numerical computation of diffraction diagrams for various incoming waves within the fluid, and for various wedge angles. the strategy may be utilized to any challenge of coupled waves via a wedge interface. This paintings is of curiosity for any researcher all in favour of excessive frequency wave scattering, particularly mathematicians, acousticians, engineers.
