s2p -> ADS, calculate Z abnormal, calculate Y & S normal. Why? Thanks!

The Z-parameter matrix does not exist because some or all of the Z-parameters are infinite. Setting all Z-parameters
to zero.

Z parameters (Impedance parameters) provide a measure of the impedances through the different parts of the electrical network. S parameters provide measurements of voltage wave ratios through an electrical network. Using dB notation make sense for the S parameter ratios. However, it does not make sense for z parameters so these should never be expressed in dB.
