Hello, it sounds like you should use the "s coefficients" option, not the "s parameter" option. The "s parameter" option is used when directly specifying the S parameters as a function of frequency. The "s coefficients" option is used when writing the S parameters as a ratio of polynomials. You can use complex parameters with the "s coefficients" option. You also might need to change the order of the parameters in your matrix.
