Functions

mhd_waves(*args, **kwargs)

Returns a dictionary containing objects of the three magnetohydrodynamic waves with identical parameters.

stix(B, w, ions, n_i, theta)

Calculate the cold plasma dispersion function presented by Stix [1992], and discussed by Bellan [2012].

two_fluid(B, ion, k, n_i, theta, *, T_e, T_i)

Using the solution provided by Bellan [2012], calculate the analytical solution to the two fluid, low-frequency (\(ω/kc ≪ 1\)) dispersion relation presented by Stringer [1963].
