Figure 15. Original elastic wavefield in , , and planes generated from the stiffness tensor coefficients of the two-layered heterogenous triclinic model (equation 29) a) x-component b) y-component c) z-component. One can observe more complicated S-wave behaviors that those in the homogeneous orthorhombic model (Figure 7) and homogeneous triclinic model (Figure 15). |

Figure 16. Separated y-component of S1 elastic wavefield in the two-layered heterogenous triclinic model (equation 29) with equal to a) 0 (no smoothing) b) 0.2. The final seprated wavefield with amplitude compensation (equation 28) is shown in c). Notice planar artifacts disappearing when the proposed smoothing filter is applied as shown in b) and with the restored amplitude asshown in c). The clipping has been adjusted to enhance visualization and stay constant in all three plots. |
