Impedance Matrix

Recommended Posts

Hi Bidisha


From your description I assume that you would like to extract the multi-port Z-parameters. (Note that the "MoM Matrix" solved during the Method of Moments solution in Feko is also known as the "Impedance matrix" as the elements of this matrix have the the same units and impedance.)


To extract the Z-parameters you should request S-parameters in CADFEKO and then, after the simulation has completed, in POSTFEKO use the Export -> Touchstone option. Under the Touchstone export dialog there is an option to select the "Network parameter type" for the export. There you should select "Z (impedance parameters)" to then export the data to a Touchstone file.


Kind regards,

Johan H
