The effect of parameter on the real and imaginary parts of amplitude reflection coefficients of waves 1 and 2 (a, d), phase differences ϕ1,2, δ, angle θ (b, e) and trajectories of the tips of vectors r 1,2 on the complex plane (c, f). The main layer thickness is: d2 = 5 nm (a, b, c), 50 nm (d, e, f). The values of parameters for all the graphs are: ψ = 0, d1,3,4 = 0, λ = 650 nm, , μβ = 1, the main layer material is vanadium dioxide. The black horizontal dashed line in a, b, d, e characterizes equality to zero of the corresponding quantities. The explanations of characteristic points in all the graphs (the points are denoted by small squares and circles) are given in a, b. The arrows in figs. c, f point to the direction of motion on the trajectories (c, f) for increasing values. Parameters and are used as the abscissa axis for graphs (a, b, d, e) and (c, f), correspondingly.
