Dependences of angle θ (a, f), PSD of the reflected waves (b, d, g, i) and corresponding energy reflection coefficients (c, e, h, k) on parameter for various PCMs (amorphous and crystalline GST 225, VO2) as the main layer material. The values of parameters are: d2 = 5 nm (a–e), 50 nm (f–k). The values of parameters for all the graphs are: ψ = 0, λ = 650 nm, d1,3,4 = 0, , μβ = 1. d, e, i, k detail the corresponding graphs for the cases of optimal parameters. The black horizontal dashed line in (b) corresponds to the condition Δϕ = 0. Parameter is used as the abscissa axis for all the graphs.
