The scattering matrix parameters (S-parameters) of a two-port network are given with reference to a characteristic impedance Z0. If two lossless transmission line sections of electrical lengths θ1 = βl1 and θ2 = βl2 are added to the input and output ports respectively, the modified S-parameters matrix [S'] of the resultant network is given by:
