The dispersion relation for surface waves on an impermeable boundary of a fully saturated
poroelastic medium is investigated numerically over the whole range of applicable
frequencies. To this aim a linear simplified model of a two-component poroelastic medium is
used. Similarly to the classical Biot's model, it is a continuum mechanical model but it is
much simpler due to the lack of coupling of stresses. However, results for bulk waves
following for these two models agree very well indeed which motivates the application of the …
