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

Crystals, 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-

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

Anales (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

An ultra-thin high-efficiency plasmonic metalens with symmetric split ring transmitarray metasurfaces

Results in Physics, 2023
Metasurface lenses (or metalenses) have aroused great attentions and efforts in the community of metamaterials or metasurfaces due to its ultrathin device dimension and superior focusing performances. High-efficiency transmissive metalenses with an ultra-

Effects of scattering and dust grain size on the temperature structure of protoplanetary discs: A three-layer approach

, 2008
The temperature in the optically thick interior of protoplanetary discs is essential for the interpretation of millimeter observations of the discs, for the vertical structure of the discs, for models of the disc evolution and the planet formation, and ...

Fractal scattering in a radiation field [PDF]

Physical 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.

Ultrathin MWCNT/Ti₃C₂T_x Hybrid Films for Electromagnetic Interference Shielding

Nanomaterials
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

Local bonds anomalies and dynamics in bismuth ferrite

AIP Advances, 2017
The temperature evolution of the chemical and magnetic sublattice of bismuth ferrite has been investigated by neutron scattering below room temperature. Although the bulk lattice structure performed as expected, anomalies were measured in the local Bi-Fe

Radiation and Scattering [PDF]

, 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
