skrf.network.s2t

skrf.network.s2t(s)

Converts scattering parameters 1 to scattering transfer parameters 2 .

transfer parameters are also referred to as ‘wave cascading matrix’ 3, this function only operates on 2N-ports networks with same number of input and output ports, also known as ‘balanced networks’.

Parameters

s (numpy.ndarray (shape fx2nx2n)) – scattering parameter matrix

Returns

t – scattering transfer parameters (aka wave cascading matrix)

Return type

npy.ndarray
