Reflection and refraction from a vertical layer of surface SH-waves radiated from a point source on a free from tensions boundary
With the help of the asymptotic boundary layer method, the transformation of an elastic SH-polarized surface wave of whispering gallery type (the so-called Love wave) is analyzed in the case where this wave passes many times through a vertical layer between two half-planes
Boundary layer method in the problem of far propagation of surface SV-waves
The SV polarized wave field is investigated in an elastic gradient layer of constant width. A point source is situated on the boundary of the layer. Rigid contact conditions are assumed to be valid on the boundary between the layer and an elastic half-space. It is shown that the interference field in the principal approximation far from the source does not depend on the relation between the phase velocity and the transversal and longitudinal velocities in the half-space
