Coherence effects in Mie scattering [PDF]
Journal 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.

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

Effective Scatterer Diameter Estimates for Broad Scatterer Size Distributions [PDF]
Ultrasonic Imaging, 2014 Acoustic form factors have been used to model the frequency dependence of acoustic scattering in phantoms and tissues. This work demonstrates that a broad range of scatterer sizes, individually well represented by Faran theory or a Gaussian form factor, is not accurately described by a single effective scatterer from either of these models ...

Research on High Power Remote Pump Transmission System
Guangtongxin 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 ...

Skew scattering due to intrinsic spin-orbit coupling in a two-dimensional electron gas [PDF]
, 2007 We present the generalization of the two-dimensional quantum scattering formalism to systems with Rashba spin-orbit coupling. Using symmetry considerations, we show that the differential scattering cross section depends on the spin state of the incident ...

Extrapolated Speckle-Correlation Imaging
Intelligent 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 ...

All-optical scattering control in an all-dielectric quasi-perfect absorbing Huygens’ metasurface
Nanophotonics, 2022 In this paper, we theoretically and experimentally demonstrated photothermal nonlinearities of both forward and backward scattering intensities from quasi-perfect absorbing silicon-based metasurface with only λ/7 thickness. The metasurface is efficiently

Modern nuclear force predictions for the neutron-deuteron scattering lengths [PDF]
, 2003 The nd doublet and quartet scattering lengths have been calculated based on the modern NN and 3N interactions. We also studied the effect of the electromagnetic interactions in the form introduced in AV18. Switching them off for the various nuclear force
