Figure 2   Variations of phase velocity for symmetric leaky Lamb waves
Figure 3   Variations of phase velocity for skew-symmetric leaky Lamb waves
Fig. 4 shows that for (n=0) symmetric mode of propagation, the velocities for GANLS are greater  than GNLS for  ξ d = 2, 4 ≤ ξ d ≤ 6, 8 ≤ ξ d ≤ 10  and in the remaining region, the behavior is  op-posite
