skrf.tlineFunctions.load_impedance_2_reflection_coefficient(z0, zl)¶

Returns the reflection coefficient for a given load impedance, and characteristic impedance.

For a transmission line of characteristic impedance $Z_0$ terminated with load impedance $Z_l$ , the complex reflection coefficient is given by,

$\Gamma = \frac {Z_l - Z_0}{Z_l + Z_0}$

Parameters :

z0 : number or array-like

characteristic impedance

zl : number or array-like

load impedance (aka input impedance)

Returns :

gamma : number or array-like

reflection coefficient
