| Abstract |
The classical problem of scattering of a high-frequency wave from a point
source in an elastic medium by an arbitrary smooth nonconvex free boundary
surface of the elastic body is studied in view of possible multiple
reflections. The analysis is based on estimates of multiple diffraction
integrals by the multidimensional stationary phase method. We obtain
closed-form expressions for the leading term in the asymptotics of the
displacement amplitudes in reflected waves for various possible
combinations of reflection and transformation of longitudinal and
transverse waves by nonconvex parts of the boundary surface. |
