skrf.network.s2vswr_active
- skrf.network.s2vswr_active(s, a)[source]
Return the active VSWR for a defined wave excitation a..
The active VSWR is defined by :
\[\mathrm{active}(vswr)_{m} = \frac{1 + |\mathrm{active}(s)_m|}{1 - |\mathrm{active}(s)_m|}\]where \(\mathrm{active}(s)_m\) the active S-parameter of port \(m\).
- Parameters:
s (complex array) – scattering parameters (nfreqs, nports, nports)
a (complex array of shape (n_ports)) – forward wave complex amplitude
- Returns:
vswr_act – active VSWR for the excitation a
- Return type:
complex array of shape (nfreqs, nports)
