Reflection and Transmission of Waves at a Fluid/Porous-Medium Boundary

摘要

Relatively simple closed-form expressions axe derived for the reflection and transmission coefficients belonging to a fluid/porous-medium interface with open-pore boundary conditions. The wave propagation in the fluid-saturated porous-medium is described using Biot's theory and it is assumed that both the porous skeleton and the pore fluid are much more compressible than the skeletal solid grains themselves. The obtained results find their application in forward and inverse surface wave analysis.
