Normalized transverse perturbations of velocity of charges (top row), velocity of neutrals (middle row), and magnetic field (bottom row) at the time t = 15τ for Alfvén waves (left column), ion-cyclotron waves (center column), and whistler waves (right column) with a period of τ = 0.02 s and amplitude Ac = 0.01 cA,T. Case of a plasma with np = 1.4 × 1015 m−3, χ = 100, B0 = 10 G, and νnc = 100ω. Symbols represent the results from numerical simulations (diamonds: x-component; crosses: y-component), while lines represent the analytical expressions given by Equations (18) and (19).
