Diffraction in the semiclassical description of mesoscopic devices [PDF]

, 1997
In pseudo integrable systems diffractive scattering caused by wedges and impurities can be described within the framework of Geometric Theory of Diffraction (GDT) in a way similar to the one used in the Periodic Orbit Theory of Diffraction (POTD).

Analytical Model for Optical Scattering of Infrared Laser by Nonspherical Raindrops

International Journal of Optics, 2015
Analytic model was developed to investigate the interaction of infrared laser with nonspherical raindrops. The method based on Fraunhofer diffraction and geometrical optics was presented to obtain the analytic solution for single-scattering properties by

Diffraction Patterns in Deeply Virtual Compton Scattering [PDF]

, 2006
We report on a calculation to show that the Fourier transform of the Deeply Virtual Compton Scattering (DVCS) amplitude with respect to the skewness variable \zeta at fixed invariant momentum transfer squared t gives results that are analogous to the ...

Diffractive hard scattering [PDF]

Nuclear Physics B, 1987
Abstract We discuss high energy hadron collisions that contain a hard scattering, in the sense that a W, a Z, very heavy quarks, or high p T jets are produced, yet are diffractive, in the sense that one of the incident hadrons is scattered with only a small energy loss.

A Tutorial on the Classical Theories of Electromagnetic Scattering and Diffraction

Nanophotonics, 2020
Starting with Maxwell’s equations, we derive the fundamental results of the Huygens-Fresnel-Kirchhoff and Rayleigh-Sommerfeld theories of scalar diffraction and scattering.

Elastic Scattering by Deterministic and Random Fractals: Self-Affinity of the Diffraction Spectrum

, 1996
The diffraction spectrum of coherent waves scattered from fractal supports is calculated exactly. The fractals considered are of the class generated iteratively by successive dilations and translations, and include generalizations of the Cantor set and ...

High Accuracy Scattering Center Modeling Based on PO and PTD [PDF]

Radioengineering, 2018
Based on the solutions of physical optics (PO) and physical optics of diffraction (PTD), we propose a modified parametric scattering center model for high precise signal simulations of extended targets.

Refining short-range order parameters from the three-dimensional diffuse scattering in single-crystal electron diffraction data

IUCrJ
Our study compares short-range order parameters refined from the diffuse scattering in single-crystal X-ray and single-crystal electron diffraction data. Nb0.84CoSb was chosen as a reference material.

Four-dimensional imaging of lattice dynamics using ab-initio simulation

npj Computational Materials, 2021
Time-resolved mapping of lattice dynamics in real- and momentum-space is essential to better understand several ubiquitous phenomena such as heat transport, displacive phase transition, thermal conductivity, and many more.
