Plots of logarithm of normalized Landau damping versus normalized axial wave number kc / ω _pe for panel (a1) EH₀₁ mode, panel (a2) C₀₁ mode, and panel (a3) SC₀₁ mode, where the solid, dashed, and dotted curves represent three different values of normalized electron thermal velocity: (a1) (0.03, 0.02, 0.01), (a2) (0.003, 0.002, 0.001), and (a3) (0.03, 0.02, 0.01) respectively; (b) plots of logarithm of normalized Landau damping versus normalized axial wave number kc / ω _pe for panel (b1) EH₀₁ mode, panel (b2) C₀₁ mode, and panel (b3) SC₀₁ mode, where the solid, dashed, and dotted curves represent three different values of normalized plasma radius (0.7, 0.65, 0.6), respectively; plots of logarithm of normalized Landau damping versus normalized axial wave number kc / ω _pe for (c1) EH₀₁ mode and (c2) SC₀₁ mode, where the solid, dashed, and dotted curves represent three different values of normalized cyclotron frequency (1.86, 1.63, 1.40), respectively.
