# plasmapy.dispersion.analytical.two_fluid_

This module contains functionality for calculating various analytical solutions to the two fluid dispersion relation.

## Functions

 two_fluid(*, B, ion, k, n_i, T_e, T_i, theta) Using the solution provided by Bellan [2012], calculate the analytical solution to the two fluid, low-frequency ($$\omega/kc \ll 1$$) dispersion relation presented by Stringer [1963].
