Dependences of PSD Δϕ, ΔΦ, energy transmission coefficients T_1,2 of waves 1, 2 on parameters (a, c) and (b, d) for various materials of layers 1, 3 and anisotropic materials of the main layer. The values of parameters are: (a) ε₁ = ε₃ = 0.01 + 0.01i, , , d_1,3 = 250 nm, d₂ = 28 nm, λ = 0.63 μm; (b) ε₁ = ε₃ = 0.01 + 0.01i, , , d_1,3 = 250 nm, d₂ = 28 nm, λ = 0.63 μm; (c) ε₁ = ε₃ = − 13 + 0.5i, , , d_1,3 = 13 nm, d₂ = 156 nm, λ = 0.6 μm; (d) ε₁ = ε₃ = − 13 + 0.5i, , , d_1,3 = 13 nm, d₂ = 156 nm, λ = 0.6 μm. The values of parameters for all the graphs are: ε_α,β = 1; ψ = 0. The black horizontal dashed line in all the figures characterizes equality to 0 of the corresponding quantities. TM polarization of the incident wave is used.
