Definition

A frequency‑domain linear model that expresses, for each port, how incident (a) and reflected (b) travelling‑wave amplitudes relate via an S‑parameter matrix under specified reference impedances; widely used to characterize high‑frequency linear components where wave propagation and port matching matter.
