Normalized imaginary EM field Im(E_x/v_AB_y) as a function of the normalized perpendicular wavenumber k_⊥ρ_i for different values of κ. The parameters’ values appropriate for the solar coronal region are; v_A ≈ 1.85 × 10⁸ cm/sec, v_Ti ≈ 1.9 × 10⁷ cm/sec, v_Te ≈ 1.34 × 10⁹ cm/sec, k_⊥/k_∥ = (100 − 115) (Chen & Wu 2012), magnetic field B = (50 − 100) G (Zirin 1996; Gary 2001), and temperature T > 10⁶ Kelvin (De Moortel & Browning 2015), respectively. In the left panel, the ratio of electron-to-ion temperature is 0.5, and in the right panel, T_e/T_i ≈ 0.4. The black curve (κ → ∞) represents the Maxwellian result.
