# skrf.tlineFunctions.zl_2_Gamma0¶

skrf.tlineFunctions.zl_2_Gamma0(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) gamma – reflection coefficient number or array-like
