This paper describes the scattering matrix approach to obtain the solution to electromagnetic field quantities in harmonic multi-layer models. Using this approach, the boundary conditions are solved in such way that the maximum size of any matrix used during the computations is independent of the number of regions defined in the problem. As a result, the method is more memory efficient than classical methods used to solve the boundary conditions. Because electromagnetic sources can be located inside the regions of a configuration, the scattering matrix formulation is developed to incorporate these sources into the solving process. The method is applied to a 3D electromagnetic configuration for verification.

The non-local manipulation of spin-entangled states by means of local gating in two parallel 2D topological insulators properly connected to two superconducting electrodes is studied. We calculate analytically the current-phase relationship of the Josephson current making use of the scattering matrix approach and we identify the various local and non-local scattering mechanisms. We show that the Josephson critical current, remarkably, allows a direct quantification of the entanglement manipulation.

The electromagnetic–acoustic field in a waveguide filled with a magnetoplasma (or in a stratified magnetoplasma), as well as the corresponding formally adjoint field, are decomposed into eigenmodes. The amplitudes of incoming and outgoing modes for both fields are related by scattering matrices. It is shown that the transposed scattering matrix of one field is the inverse scattering matrix of the other. The fictitious formally adjoint field is temporally mapped into a physical Lorentz-adjoint field, whose scattering matrix is shown to be the transpose of the scattering matrix of the original field.
