Nonlinear Effects of Electromagnetic TM Wave Propagation in Anisotropic Layer with Kerr Nonlinearity

Figure 4

Plot of 𝛾(ℎ). The first few dispersion curves are shown. Solid curves for the nonlinear case (solutions of (7.14)); dashed curve for the linear case (solutions of (8.5)). The following parameters are used for both cases: 𝜀₁=1, 𝜀₂=−1.5, 𝜀₃=1, and for the nonlinear case 𝑎=5.2 and 𝐸_𝑧^(ℎ)=1. Dashed lines are described by formulas: ℎ^∗=1.71 (thickness of the layer), 𝛾=1 (lower bound for 𝛾) and 𝛾=3 (upper bound for 𝛾 in the case of linear medium in the layer).
