Figure 2

Collection design of isotropic model. Consider (a) and snapshots at 0.2 s, (b) is full elastic wave field of horizontal component, (c) is full elastic wave field of vertical component, (d) is the separated pure P-wave of horizontal component, (e) is the separated pure P-wave of vertical component, (f) is the pure P-wave based on divergence operator, (g) is the separated pure S-wave of horizontal component, (h) is the separated pure S-wave of vertical component, and (i) is the pure S-wave based on curl operator.
