# S-matrix using python API

Hello again,

I am running my EME through the python API and hope to get the internal s-parameters. I’ve tried

getresult(“EME”, “user s-matrix”)
getresult(“EME”, “internal s-matrix”)

but both of these do not work. Can these be accessed via the API?

Thanks,
Ian

Hello @ihammond,

There is no “-” in the names of the S matrix results, the commands mode.getresult("EME", "user s matrix") and mode.getresult("EME", "internal s matrix") should work if you have performed the EME propagation.

I hope this helps. Let me know if you have any questions.
