Thank you,sir.
[1]At first I re-calculate your script and get the same plot.
[2]Then I compare mine setup with yours , finding two big differences:1.In A direction, your boundary condition is [Dirichlet, Neumann], while mine is [Neumann, Neumann]
2.you get the plot by append( transmission_spectrum.conductance().inUnitsOf(Siemens) * 1e6 ), which I don't understand. while, I get the plot by Analyzer>Analyzers>Conductance>Drop NC files.
[3]Attached is my script with your setup, and Analyzer--produced plot, the plot have different unit. Please tell where i am wrong in ploting.
[4]Here is the experiments results http://quantumwise.com/forum/index.php?topic=1713.0
As is shown, your calculation is still in contradict with the experiments. This needs more discussion and hope to get more attention.
