Nonlinear Scattering Matrix in Quantum Optics
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.

The polarimetric synthetic aperture radar (PolSAR) provides us with a two-by-two scattering matrix data set. The ensemble averaged coherency matrix in an imaging window derived using a scattering matrix has all non-zero elements in its three-by-three ...

Scattering in Algebraic Approach to Quantum Theory—Associative Algebras
The definitions of scattering matrix and inclusive scattering matrix in the framework of formulation of quantum field theory in terms of associative algebras with involution are presented. The scattering matrix is expressed in terms of Green functions on

Generalization of the mode-matching technique to the problems of scattering by semi-infinite slow-wave structures [PDF]
Subject and purpose. The scattering matrix of a semi-infinite slow-wave structure formed by grooves in a rectangular waveguide is investigated. The purpose was to develop a method for calculating a semi-infinite periodic structure.

Geometry and entanglement in the scattering matrix [PDF]
A formulation of nucleon-nucleon scattering is developed in which the S-matrix, rather than an effective-field theory (EFT) action, is the fundamental object. Spacetime plays no role in this description: the S-matrix is a trajectory that moves between RG

Synergistically engineered 2D MXenes for metal-ion/Li–S batteries: Progress and outlook
MXenes are a two-dimensional (2D) class of transition metal carbides, nitrides, and carbonitrides that have been synthesized and developed for diverse purposes, such as energy storage devices.

The Scattering Matrix of a Graph [PDF]
Recently, Smilansky expressed the determinant of the bond scattering matrix of a graph by means of the determinant of its Laplacian. We present another proof for this Smilansky's formula by using some weighted zeta function of a graph. Furthermore, we reprove a weighted version of Smilansky's formula by Bass' method used in the determinant expression

Non-invasive focusing and imaging in scattering media with a fluorescence-based transmission matrix [PDF]
In biological microscopy, light scattering represents the main limitation to image at depth. Recently, a set of wavefront shaping techniques has been developed in order to manipulate coherent light in strongly disordered materials.

How to calculate the pole expansion of the optical scattering matrix from the resonant states [PDF]
We present a formulation for the pole expansion of the scattering matrix of open optical resonators, in which the pole contributions are expressed solely in terms of the resonant states, their wave numbers, and their electromagnetic fields. Particularly,
