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

Figure 2

Plot of 𝛾(ℎ). The first few dispersion curves are shown. Solid curves for the nonlinear case (solutions of (7.14)); dashed curves for the linear case (solutions of (8.1)). The following parameters are used for both cases: 𝜀₁=1.44, 𝜀₂=9, 𝜀₃=1, and for the nonlinear case 𝑎=0.1, and 𝐸_𝑧^(ℎ)=1. Dashed lines are described by formulas: ℎ^∗=3.206 (thickness of the layer), 𝛾=1.2 (lower bound for 𝛾), and 𝛾=3 (upper bound for 𝛾 in the case of linear medium in the layer).
