Coherence effects in Mie scattering [PDF]

open access: yesJournal of the Optical Society of America A, 2011
The scattering of a partially coherent beam by a deterministic, spherical scatterer is studied. In particular, the Mie scattering by a Gaussian Schell-model beam is analyzed. Expressions are derived for (a) the extinguished power, (b) the radiant intensity of the scattered field, and (c) the encircled energy in the far field.

High frequency sound reduction by air shield

open access: yesNihon Kikai Gakkai ronbunshu, 2020
This paper deals with the acoustic shielding of especially high-frequency sound by jet (Air Shield). In the shear layer of the jet, sound waves incident on the jet undergo reflection and / or scattering.

A Theoretical-Study of the Scattering of Ultrasound from Blood [PDF]

open access: yesModeling, Identification and Control, 1981
A theoretical treatment of the scattering of ultrasound from blood is given, assuming that the blood behaves essentially as a continuum. The scattering then arises from fluctuations in the mass density and compressibility of the blood, which is caused by

Research on High Power Remote Pump Transmission System

open access: yesGuangtongxin yanjiu, 2021
The transmission distance of high power pump in the remote pump transmission system is limited. Considering this issue, a novel remote pump transmission scheme is proposed based on the principle of the randomly distributed feedback fiber laser, which ...

Influence of Ag@SiO2 with Different Shell Thickness on Photoelectric Properties of Hole-Conductor-Free Perovskite Solar Cells

open access: yesNanomaterials, 2020
In this paper, Ag@SiO2 core-shell nanoparticles (NPs) with different shell thicknesses were prepared experimentally and introduced into the photosensitive layer of mesoscopic hole-conductor-free perovskite solar cells (PSCs) based on carbon counter ...

Extrapolated Speckle-Correlation Imaging

open access: yesIntelligent Computing, 2022
Imaging through scattering media is a longstanding issue in a wide range of applications, including biomedicine, security, and astronomy. Speckle-correlation imaging is promising for noninvasively seeing through scattering media by assuming shift ...

On the scattering Aharonov–Bohm effect [PDF]

open access: yesPhysica Scripta, 2019
Abstract In this paper we review some aspects of the scattering Aharonov–Bohm effect and Berry’s phase. Specifically, the problem of scattering of free 2d electrons on the system of an arbitrary number of parallel, infinitely thin and infinitely long coils (non-interacting, point magnetic fluxes) is modeled as free semi-classical ...

Acoustic scattering reduction in elastic materials with Bat optimization algorithm

open access: yesJournal of Mechanical Engineering and Sciences, 2021
A scattering-cancelation method is followed in this analysis. The opportunity to reduce the scattering effect in rigid cylinder with elastic cloaking material is investigated in the paper.

Light scattering in colloidal dispersions: Effects of multiple scattering

open access: yesJournal of Colloid and Interface Science, 1985
We outline the derivation of expressions for higher-order scattered electric field strengths, including both multiple inter- and intraparticle scattering events, although only the former are of practical interest. Next an ensemble-averaging procedure for calculating the averages of second-order quantities is proposed and subsequently applied to derive ...
