It is well known that the scattering matrix plays an important role in quantum optics. This matrix converts the incoming characteristics of scattered radiation into output characteristics. Currently, only special cases of such a scattering matrix are known, which are determined by a specific problem...
The quantum theory of the optical birefringence induced in molecular gases by external fields is discussed in a general setting. The scattering of light by molecules is expressed by the generalized Kramers-Heisenberg formula for the R-matrix element, and the Stokes parameter formalism is used to ...

The patterns of the scattering layer represent its transmission matrix, which is a complex-value matrix. We primarily evaluate the randomness of the phase component, which is mapped to the range of 0–255 and then converted to an 8-bit binary code. The NIST standards30, which comprises 15 ...
For classical chaotic scattering, the S-matrix elements in the semiclassical regime exhibit random fluctuations [173,348] with respect to variations in parameters such as the particle energy or the strength of an external magnetic field in a classically small but quantum-mechanically large range. In...
We are thus able to approximate the scattering matrix for waves incident on the bend accounting for tunnelling mediated by resonant states and uniformly treating the transition between the limits of totally reflected and totally transmitted waves....
The spin–orbit coupling effects can then be represented in a scattering matrix that relates the spin–orbit coupling stationary states in different leads. We apply this new formalism to the case of a four-port beamsplitter, and it is shown to mix states with different spin–orbit coupling ...
