Reduction of the scattering matrix array

The scattering matrix approach is widely used in wave engineering and quantum physics. Usually, a combination of multiple scattering matrices is used. In this article we consider arbitrary arrays of interconnected scattering matrices and present a formal result for the reduced scattering matrix. We demonstrate this approach in two well-known scattering problems.
