skrf.network.inv¶
- skrf.network.inv(s)[source]¶
Calculates ‘inverse’ s-parameter matrix, used for de-embedding
This is not literally the inverse of the s-parameter matrix. Instead, it is defined such that the inverse of the s-matrix cascaded with itself is a unity scattering transfer parameter (T) matrix.
\[inv(s) = t2s({s2t(s)}^{-1})\]where \(x^{-1}\) is the matrix inverse. In words, this is the inverse of the scattering transfer parameters matrix transformed into a scattering parameters matrix.
- Parameters
s (
numpy.ndarray(shape fx2nx2n)) – scattering parameter matrix.- Returns
s’ – inverse scattering parameter matrix.
