Dispersion surfaces obtained with the numerical linearized Vlasov-Maxwell solver WHAMP, for a homogeneous, magnetized, and Maxwellian plasma (Roennmark 1982), for n_e = 1.4 cm⁻³, T_e = 2 eV, B = 132 nT, (f_pe/f_ce = 2.88) presented all together (left) and separately, with color indicating the ratio of the magnetic to electric field (right) on a logarithmic scale. The frequency is normalized to electron plasma frequency, and the wave numbers, presented on a logarithmic scale, to the Debye length.
