skrf.tlineFunctions.load_impedance_2_reflection_coefficient(z0, zl)[source]

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 – reflection coefficient

Return type:

number or array-like
