General quantum theory of Thomson scattering

open access: yesResults in Physics, 2023
It is well known that the interaction of radiation with matter can be described using classical or quantum physics in relation to three systems: incoming radiation, matter, and scattered radiation.

Fractal scattering in a radiation field [PDF]

open access: yesPhysical Review E, 2011
We examine the transfer matrix and the stepping times for chaotic scattering of the excess electron in the chlorine ion Cl(-) from the chlorine atom. We use this information to determine the fraction of incident trajectories that are reflected and transmitted for those electrons caught in the tendrils of the chaotic scattering process.

Far-field sound radiation due to an installed open rotor [PDF]

open access: yes, 2012
Future single rotation propeller and contra-rotating advanced open rotor concepts promise a significant fuel efficiency advantage over current generation turbofan engines.

On the Usage of Tapered Undulators in the Measurement of Interference in the Intensity-Dependent Electron Mass Shift

open access: yesCrystals, 2021
In nonlinear Thomson scattering, the main emission line and its harmonics form a band-like structure due to the laser pulse shape induced ponderomotive broadening. We propose to use tapered undulators to mimic Thomson scattering and measure the intensity-

Scattering of circularly polarized radiation [PDF]

open access: yesThe Journal of Physical Chemistry, 1983
The differential refraction and absorption of circularly polarized light was applied by Henry Eyring and co-workers to study the configuration and conformation of small molecules. The differential scattering as a function of angle of circularly polarized light can provide structural information about large scattering systems.

Laplace-transform-based method to calculate back-reflected radiance from an isotropically scattering half-space [PDF]

open access: yes, 1997
We present a method to determine the back-reflected radiance from an isotropically scattering half-space with matched boundary. This method has the advantage that it leads very quickly to the relevant equations, the numerical solution of which is also ...

EFFECT OF INTENSE MAGNETIC FIELDS ON THE TRAJECTORY OF ELECTRONSPROPAGATING IN LOW DENSITY MEDIA OF INTEREST FOR MRI-LINAC RADIOTHERAPY

open access: yesAnales (Asociación Física Argentina), 2023
Ionizing radiation transport mechanisms in presence of magnetic fields can be described in terms of formalisms based on the Boltzmann radiation transport equation. However, when the transport occurs not in vacuum but in scattering media the difficulty of

Calculation of the radiance distribution at the boundary of an isotropically scattering slab [PDF]

open access: yes, 1997
The radiance arising from an anisotropically scattering illuminated stack of n slabs is calculated using the equation of radiative transfer. It appears to be unnecessary to calculate the radiance inside the material; including only the radiance at the ...

Ultrathin MWCNT/Ti3C2Tx Hybrid Films for Electromagnetic Interference Shielding

open access: yesNanomaterials
The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit the application of electromagnetic interference (EMI) shielding. In this work, an ordered lamellar assembly structure of multiwalled carbon nanotube/Ti3C2Tx

Radiation and Scattering [PDF]

open access: yes, 2017
AbstractAt this point, we have made a rather extensive investigation into the sounds that excite Helmholtz resonators as well as the departures from equilibrium that propagate as plane waves through uniform or inhomogeneous media. We have not, as yet, dealt with how those sounds are actually produced in fluids. Our experience tells us that sound can be
