| dc.description | This paper concerns the total internal reflection of an elastic wavefield at the boundary between a compressible fluid and an adjacent elastic solid. The system is forced by a prescribed high-frequency wave incident upon the interface from the fluid and emphasis is placed on the construction of the local acoustic response near the points where the shear or longitudinal components of the total elastic field propagate tangentially to the boundary. A methodology for this construction, which is based on multiple-scales techniques, is presented and detailed calculations are carried out for both flat and curved interfaces. These analyses not only yield local amplitude balances and governing solutions but also furnish certain diffraction coefficients which might be of importance in other global scattering problems involving coupled fluid-solid configurations. |
