how to calculate s parameters
EM solvers like HFSS, CST MWS, IE3D, ADS Momentum etc can easily calculate multi-port S-parameters over a large frequency range. Does anyone implemented or knows the detailed similar algorithms to extract the S-parameter using some numerical methods like RWG based triangle-discritized patch using MOM?
There are a lot of detailed publications talking about the calculation of the far-field from the obtained current density coefficients in the scattering/radiation area, but little was found to get the S-parameters for the simple RF/microwave circuits such as microstrip filters, baluns, couplers etc.
Thank you in advance for your reply and sharing of the experience, if any!
