Dispersion diagrams for (a) \(\gamma =0\), (b) \(\gamma =0.563\), (c) \(\gamma =1\) and (d) \(\gamma =1.406\). In the calculations the following parameters are chosen: \(c=0.8\), \(\alpha =0.5\) and \(G=0, 1, 1.778\) and 2.5 [in parts (a–d), respectively]. Note that \(\gamma = G\alpha (c+1)/(4c(1-\alpha ))\).
