(electricity)
A matrix Z whose elements are the mutual impedances between the various meshes of an electrical network; satisfies the matrix equation V = ZI, where V and I are column vectors whose elements are the voltages and currents in the meshes.

For fiber lining, the absorption is modeled using a complex impedance matrix expressed in modal coordinates to describe the impedance of the lining on the acoustic cavity.
While using an impedance matrix to define a network might be more intuitive, it is actually more difficult to get the proper measurements; therefore, S-Parameters are the choice of the digital designer.
Rather than expressing the relationship between a's and b's in terms of a nonlinear large-signal scattering matrix S, we can alternatively express the relationship between voltages (V's) and currents (I's) in terms of a nonlinear large-signal impedance matrix Z, as follows
