Fig. 6

Stability regions obtained from the analysis of Eq. (79). The plots are generated using the parameters \(\mu _1 = 0.7\), \(\mu _2 = 0.6\), \(\mu _3 = -0.7\), \(\alpha _1 = 0.8\), \(\alpha _2 = 0.5\), and \(\eta = 1.0\). The phase parameter is fixed as \(\phi =-2.7\) in subfigure (b), \(\phi =-30\) in subfigure (c), and a combined representation of both cases is displayed in subfigure (d). The normalized wave numbers are chosen as \(\mathcal {L}_1 = 1.0\) and \(\mathcal {L}_2 = 0.5\). These diagrams highlight stability zones in the parameter space, confirming the analytical stability analysis presented in Sect.  4.
