acoustotreams.AcousticTMatrix.xs_sca_avg

property AcousticTMatrix.xs_sca_avg

Rotation-averaged scattering cross section (m^2).

The average is calculated as

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

where \(k\) is the angular wavenumber in the background medium.

It is only implemented for global T-matrices.

Returns:

float or complex
