Active scattering parameter matrix.

Active scattering parameters are simply inverted s-parameters, defined as a = 1/s. Useful in analysis of active networks. The a-matrix 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 a11 can be accessed by taking the slice a[:,0,0].

Returns:a – the active scattering parameter matrix.
Return type:complex numpy.ndarray of shape fxnxn
