A deep neural network for general scattering matrix [PDF]
Nanophotonics, 2023 The scattering matrix is the mathematical representation of the scattering characteristics of any scatterer. Nevertheless, except for scatterers with high symmetry like spheres or cylinders, the scattering matrix does not have any analytical forms and ...

Inclusive scattering matrix and scattering of quasiparticles [PDF]
Nuclear Physics B, 2020 The quantum theory can be formulated in the language of positive functionals on Weyl or Clifford algebra (L-functionals). It is shown that this language gives simple understanding of diagrams of Keldysh formalism (that coincide in our case with the ...

Exploiting the speckle-correlation scattering matrix for a compact reference-free holographic image sensor. [PDF]
Nat Commun, 2016 The word ‘holography’ means a drawing that contains all of the information for light—both amplitude and wavefront. However, because of the insufficient bandwidth of current electronics, the direct measurement of the wavefront of light has not yet been ...

World Scientific Lecture Notes in Physics, 1993 As a student of circuit theory, I have always found the scattering matrix to be shrouded in mystery. Reading books, unfortunately, did not help me. This article is a ground-up attempt to uncover the mysteries behind the scattering matrix, and to provide ...

Numerical methods for calculating poles of the scattering matrix with applications in grating theory [PDF]
Journal of Lightwave Technology, 2012 Waveguide and resonant properties of diffractive structures are often explained through the complex poles of their scattering matrices. Numerical methods for calculating poles of the scattering matrix with applications in grating theory are discussed.

Nonlinear harmonic wave manipulation in nonlinear scattering medium via scattering-matrix method
Advanced Photonics, 2023 . Scattering of waves, e.g., light, due to medium inhomogeneity is ubiquitous in physics and is considered detrimental for many applications. Wavefront shaping technology is a powerful tool to defeat scattering and focus light through inhomogeneous media,
