pyrfu.pyrf.poynting_flux module

pyrfu.pyrf.poynting_flux.poynting_flux(e_xyz, b_xyz, b_hat)

Estimates Poynting flux at electric field sampling as

\[S = \frac{E \times B}{\mu_0}\]

if b0 is given project the Poynting flux along b0

Parameters:

• e_xyz (xarray.DataArray) – Time series of the electric field.

• b_xyz (xarray.DataArray) – Time series of the magnetic field.

• b_hat (xarray.DataArray, Optional) – Time series of the direction to project the Pointing flux.

Returns:

• s (xarray.DataArray) – Time series of the Pointing flux.

• s_z (xarray.DataArray) – Time series of the projection of the Pointing flux (only if b0).

• int_s (xarray.DataArray) – Time series of the time integral of the Pointing flux (if b0 integral along b0).
