pyrfu.dispersion.one_fluid_dispersion.one_fluid_dispersion(b_0, theta, ions, electrons, n_k: int = 100)[source]#

Solves the one fluid dispersion relation.

Parameters:

  • b_0 (float) – Magnetic field

  • theta (float) – The angle of propagation of the wave with respect to the magnetic field, \(\cos^{-1}(k_z / k)\)

  • ions (dict) – Hash table with n : number density, t: temperature, gamma: polytropic index.

  • electrons (dict) – Hash table with n : number density, t: temperature, gamma: polytropic index.

  • n_k (int, optional) – Number of wavenumbers.

Returns:

  • wc_1 (xarray.DataArray) – 1st root

  • wc_2 (xarray.DataArray) – 2nd root

  • wc_3 (xarray.DataArray) – 3rd root
