Using the results of the previous problem, analyze the various modes of propagation for the particular cases
Question:
Using the results of the previous problem, analyze the various modes of propagation for the particular cases when θ = 0 and θ = π/2. Compare the results with those for a cold electron gas. Make a plot analogous to the one presented in Fig. 20.

Data from Problem 7
Consider the problem of wave propagation at an arbitrary direction in a cold magnetoplasma, but including the motion of the ions (one type only).
Show that the dispersion relation is obtained from an equation identical to (5.25), except that now we have (neglecting collisions)
where (with α = e, i)
Obtain the dispersion relation and show that it can be written in the form
where θ is the angle between k and B0, R = S + D, and L = S – D.
Determine and plot the resonances and reflection points as a function of θ.
