Hello everyone, I'm hoping someone will be able to shed some light on what I have to ask. Basically, I'm interested in the reflection of Rayleigh Waves/ Surface Waves as it travels and passes from a free surface to a surface in contact with a liquid. In particular, is there any written text or papers/ journals on this that gives the governing equations or theoretical modelling of the reflections? I've not been able to find any yet. Anything remotely related would help. Thanks in advance. Edit: Just to add, the wave first travels along an isotropic, elastic half space and then passes through a region of the half space bounded by liquid. Sort of like a surface wave moving on the surface of a table and then passes through a puddle of water.
