skrf.network.s2z(s, z0=50)¶

Convert scattering parameters [1] to impedance parameters [2]

$z = \sqrt {z_0} \cdot (I + s) (I - s)^{-1} \cdot \sqrt{z_0}$

Parameters :

s : complex array-like

scattering parameters

z0 : complex array-like or number

port impedances

Returns :

z : complex array-like

impedance parameters
