Dispersion relation obtained from the simulation (left) and KUPDAP (right). For (a, b) Θ=90∘ and (c), (d) Θ=0∘. The UHR and ECH modes appear in the ω−k plots in (a) and the Langmuir mode appears in the ω−k plots in (c) \(\Theta =90^{\circ }\) and c, b \(\Theta =0^{\circ }\). The UHR and ECH modes appear in the \(\omega -k\) plots in (a) and the Langmuir mode appears in the \(\omega -k\) plots in (c)
