skrf.network.Network.a

property Network.a: ndarray

abcd parameter matrix. Used to cascade two-ports.

The abcd-matrix [1] is a 3-dimensional numpy.ndarray which has shape fxnxn, where f is frequency axis and n is number of ports. Note that indexing starts at 0, so abcd11 can be accessed by taking the slice abcd[:,0,0].

Returns:: abcd – the Impedance parameter matrix.
Return type:: complex numpy.ndarray of shape fxnxn
