Shear wave propagation. μ1x=25kPa, μ1y=9kPa, μ2x=8Pa⋅s, μ2y=3Pa⋅s. A–D: the waveform at 4, 8, 12 and 16 ms, respectively. The area enclosed by the red square does not have PML damping. E and F: group elasticity μ1r and viscosity μ2r estimated from simulation and its comparison with Equations 22 and 23.
