skrf.network.s2y¶

skrf.network.s2y(s, z0=50)¶

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

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

Parameters :

s : complex array-like

scattering parameters

z0 : complex array-like or number

port impedances

Returns :

y : complex array-like

admittance parameters
