Good Day. I am new to the site but have a quick question.
Does Simulink have the ability to take in a 1-port S11 file and output physical modeling parameters (LCR)?
Thanks Gary

Hello Gary,
Simulink itself does not directly convert S-parameter files, such as a one-port S11 file, into physical modeling parameters like inductance (L), capacitance (C), and resistance (R). However, you can make use of MATLAB's RF Toolbox which provides functions to read and manipulate S-parameter files. You can use functions like 'sparameters' to import the S11 data.
Once the S11 data is imported, you can use additional functions to fit an equivalent circuit model to the S-parameters. This process involves using optimization techniques to estimate LCR values that match the S-parameter data.
For more details, please visit the following documentation:
Hope it helps!
