skrf.network.z2s¶

skrf.network.z2s(z, z0=50)¶

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

$s = (\sqrt{y_0} \cdot z \cdot \sqrt{y_0} - I)(\sqrt{y_0} \cdot z \cdot\sqrt{y_0} + I)^{-1}$

Parameters :

z : complex array-like

impedance parameters

z0 : complex array-like or number

port impedances

Returns :

s : complex array-like

scattering parameters
