SParametern
SParametern is a term used in electrical engineering to denote the set of scattering parameters that describe how an electrical network interacts with incident signals at its ports. It is most commonly applied to linear, time-invariant networks in the RF and microwave domain, though the concept has been extended in modern practice to address nonlinear or time-varying systems.
For an N-port network, the incident waves a_q and the reflected waves b_p are defined at frequency
Extensions: In nonlinear or time-varying networks, linear S-parameters are generalized to multi-tone or harmonic S-parameters, requiring
Measurement: SParametern are measured with vector network analyzers (VNAs) using calibration methods such as SOLT or
Applications and limitations: They underpin the design and analysis of RF components such as filters, couplers,
