treams.TMatrix.xs_sca_avg¶

property TMatrix.xs_sca_avg¶

Rotation and polarization averaged scattering cross section.

The average is calculated as

\[\langle \sigma_\mathrm{sca} \rangle = 2 \pi \sum_{slm} \sum_{s'l'm'} \frac{|T_{slm,s'l'm'}|^2}{k_s^2}\]

where \(k_s\) is the wave number in the embedding medium for the polarization \(s\). It is only implemented for global T-matrices.
