Dispersion (plasmapy.dispersion)

The dispersion subpackage contains functionality associated with plasma dispersion relations, solvers and analytical solutions.

Functions

plasma_dispersion_func(zeta)

Calculate the plasma dispersion function.

plasma_dispersion_func_deriv(zeta)

Calculate the derivative of the plasma dispersion function.

tfds_(*, B, ion, k, n_i, T_e, T_i, theta[, …])

Alias to two_fluid_dispersion_solution().

two_fluid_dispersion_solution(*, B, ion, k, …)

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.
