Dear Xavier and Anton,

Thank you a lot for your quick replies! I will try to implement it using your tips!

Cheers,
Vardan.

Hi Vardan,

This information is stored in the scattering matrix in the lead_info
attribute (see https://kwant-project.org/doc/1/reference/generated/kwant.solvers.common.SMatrix#kwant.solvers.common.SMatrix)
in the format described here:
https://kwant-project.org/doc/1/reference/generated/kwant.physics.PropagatingModes#kwant.physics.PropagatingModes

Hope that helps,
Anton
