<Electromagnetic reciprocity> relates the response obtained after exchanging source and receiver in a linear reciprocal medium. For suitably normalized ports it gives a symmetric scattering matrix. It does not require zero reflection. A magnetically biased <Faraday effect> provides an important optical example in which reciprocity can fail.
