Representation of the 2F wave energy flux contributions for the three wave periods studied in this work. From the top to the bottom in groups of two plots, the wave periods are 1 s, 3 s, and 5 s, respectively. Blue line: the magnetic energy (W_m). Green line: Acoustic energy (W_ac, α). Red line: Kinetic energy (W_K, α). Black line: Total energy (W_T). The terms of the neutrals are shown in solid lines and terms for the charges in dashed lines. We split the terms W_K, c and W_ac, c in panels separated from neutrals due to the difference in scale. The vertical dashed line indicates the equipartition layer β_plasma = 1.
