The effect of the real part of the spacer layers permittivity on the parameters of reflected (I_r, τ_r, θ_r) and transmitted (I_t, τ_t, θ_t) waves ( is used as the abscissa axis for all the graphs). The following values of parameters are used: d_1,3 = 0.15 μm, d₂ = 0.25 μm, , ε₂ = 3 +0.01i, μ₂ = 1.5 + 0.01i. The values of ψ_in and the incident wave polarization (RCP and LCP for right and left circular polarizations, here and below) are given above the corresponding graph panels. The other values of parameters correspond to the ones given in the main text (here and in the figures below).
