Comparison of the analytical results when the angle between the magnetic field and the direction of propagation is varied, corresponding to the cases shown in Figs. 7–9. Left: solutions 3 and 4 for the real part of the vertical wavenumber k_z corresponding to the cases P (θ = 25.8°), and G (θ = 45°), as well as Solution 3 for case P-f (θ = 84.2°). The vertical dot-dashed gray line at z = 1.3 Mm, which is also present in left panel of Fig. 10, marks the equipartition layer. The vertical dotted black line at z = 1.85 Mm shows the reflection height. Right: solution 3 for the imaginary part of the vertical wavenumber k_z corresponding to the three cases P (θ = 25.8°), G (θ = 45°) and P-f (θ = 84.2°), for both MHD and ambipolar cases. The points where the imaginary part diverges in the ambipolar case compared to the MHD case are indicated with markers in the panel.
