pub(crate) fn coefficient<const N: usize>(
mode: Mode,
kz: Jet<N>,
wave: Jet<N>,
pol: u8,
helicity: bool,
) -> Result<Jet<N>>Expand description
The coefficient of the spherical mode mode in a regular cylindrical wave of
polarization pol and axial wavenumber kz at one position, as a jet in kz and the
wavenumber wave: i^(l - m) sqrt(4 pi (2l + 1) / (l (l + 1))) sqrt((l - m)! / (l + m)!)
times the polarized angular function at cos theta = kz / k.
Upstream: the coefficient of treams.cw.to_sw for m equal on both sides.
