skrf.networkSet.NetworkSet.interpolate_from_network

NetworkSet.interpolate_from_network(ntw_param, x, interp_kind='linear')[source]

Interpolate a Network from a NetworkSet, as a multi-file N-port network.

Assumes that the NetworkSet contains N-port networks with same number of ports N and same number of frequency points.

These networks differ from an given array parameter interp_param, which is used to interpolate the returned Network. Length of interp_param should be equal to the length of the NetworkSet.

Parameters:

  • ntw_param ((N,) array_like) – A 1-D array of real values. The length of ntw_param must be equal to the length of the NetworkSet

  • x (real) – Point to evaluate the interpolated network at

  • interp_kind (str) – Specifies the kind of interpolation as a string: ‘linear’, ‘nearest’, ‘zero’, ‘slinear’, ‘quadratic’, ‘cubic’. See scipy.interpolate.interp1d for detailed description. Default is ‘linear’.

Returns:

ntw – Network interpolated at x

Return type:

class:~skrf.network.Network

Example

Assuming that ns is a NetworkSet containing 3 Networks (length=3) :

>>> param_x = [1, 2, 3]  # a parameter associated to each Network
>>> x0 = 1.5  # parameter value to interpolate for
>>> interp_ntwk = ns.interpolate_from_network(param_x, x0)
