skrf.network.inv

skrf.network.inv(s)

Calculates ‘inverse’ s-parameter matrix, used for de-embeding

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 unity.

where 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 fx2x2)

scattering parameter matrix.

Returns :

s’ : numpy.ndarray

inverse scattering parameter matrix.
