Dear Joe, Thanks, it is very useful for me. I want to know more about how the transmission is related to the wave vector kx, because I want to calculate the transmission contributed from some scale like kx=0~pi. So, how can i know the wave vector for "2" in S10[3, 2] ? I tried "modes = Smatrix.lead_info", it seems that it does not give the kx information. I can take graphene as an example, we have two valleys K and K' in graphene. Since the wave vectors kx for the two valleys are different, we can calculate the transmission contributed from K valley and K' valley separately, but of course we need to know "transmission-mode-kx" first. Maybe this can be easily solved in another way. Kwok-Long Lee On Fri, Feb 6, 2015 at 8:03 PM, <kwant-discuss-request@kwant-project.org> wrote:

Dear all, I want to calculate the transmission of each propagating mode separately, but I do not know how the propagating modes are related to the scattering matrix. For example, we can read from the bandstructure and find a mode at E=0.2，kx=0.95pi, how to find the transmission for this mode. Or, we have the transmission and how to find the contributions from each mode? Thanks in advance! Kwok-Long Lee
