Hi,
The S-parameters for a DGS band-stop filter by EM simulation in shown in the figure below.
The band-stop model can be easily extracted by parallel RLCs. The figure attached below shows the equivalent RLC circuit model with its frequency response.
But the S11 poles or reflection zeros are not reflected in the equivalent circuit extraction. How to fit the first 4 reflection zeros in the response of the extracted model? How can I achieve this?
Regards
