Project Description

MATLAB Script for obtaning the analytical solution for wave propagation in a homogenous poroelastic medium, based on the solution described in the paper by Dai et al. (1995).

The source used is a point explosion with time component Ricker or gaussian first derivative. The solution is computed in the frequency domain. Only non-viscous fluids are considered. The resulting seismograms are the radial components of the solid and liquid particle velocities.
