Scattering matrix S of a two-port optical system.

${H}_{L}^{+}$ and ${H}_{R}^{+}$ are the complex magnetic field amplitudes of the incoming modes at the left and right ports, respectively. Similarly, ${H}_{L}^{-}$ and ${H}_{R}^{-}$ are the complex magnetic field amplitudes of the outgoing modes from the left and right ports, respectively.
