The same test repeated with the illuminating S-wave displacement vector oriented perpendicular to fractures to simulate the propagation of a slow-S mode. Every transmitted response is a slow-S wavelet. Note how much longer the travel times are for wavelets polarized normal to fractures than they are for the wavelets polarized in 3a that are polarized parallel to fractures.
