The S-parameters are obtained by applying Fourier transform to the results of electromagnetic transient analysis.
"The S-parameters are not output in the electromagnetic transient analysis. For example, in the electromagnetic field where DC and AC mixedly exist, inductance of an element cannot be obtained. By applying Fourier transform to the results of transient analysis, S-parameters can be obtained. Also, inductance can be obtained by the L-value transform function.
