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

Figure 6

Plot of 𝛾(ℎ) for the different values of 𝑎: 1 – 𝑎=1; 2 – 𝑎=0.1; 3 – 𝑎=0.01; 4 – 𝑎=0.001; 5 – 𝑎=0.0001; 6 – 𝑎=0 (linear case). The following parameters are used for both cases: 𝜀₁=4, 𝜀₂=9, 𝜀₃=1, and for the nonlinear case 𝐸_𝑧^(ℎ)=1. Dashed lines are described by formulas: 𝛾=2 (lower bound for 𝛾), 𝛾=3 (upper bound for 𝛾 in the case of linear medium in the layer). Curves (solid) 1–5 are solutions of (7.14), and curve 6 (dashed) is solutions of (8.1).
