Light Interaction with Cluster Chiral Nanostructures by High-Order Bessel Beam

open access: yesPhotonics, 2022
Interactions between cluster chiral nanoparticles and a high-order Bessel beam (HOBB) with arbitrary illuminations are investigated. The generalized Lorenz–Mie theory (GLMT) is applied to derive the expansions of HOBB.

Investigating the significance of multiple scattering in ultrasound contrast agent particle populations [PDF]

open access: yes, 2005
The majority of the existing models describing the behavior of microbubble ultrasound contrast agents consider single, isolated microbubbles suspended in infinite media.

Influence of Refractive Index Differences on the Signal Strength for Raman-Spectroscopic Measurements of Double Emulsion Droplets

open access: yesApplied Sciences, 2022
Double emulsions show great potential for encapsulating active substances and protecting them against external influences. However, they tend to become unstable during storage.

Multiple-scattering-induced "ghost echoes" in GPM DPR observations of a tornadic supercell [PDF]

open access: yes, 2016
Evidence of multiple-scattering-induced pulse stretching for the signal of both frequencies of the Dual-Frequency Precipitation Radar (DPR) on the Global Precipitation Measurement (GPM) mission Core Observatory satellite is presented on the basis of ...

Second-Harmonic Generation in Aggregates of Lithium Niobate Particles Formed upon Suspension Freezing

open access: yesPhotonics, 2022
This paper demonstrates a significant increase in the efficiency of second-harmonic generation in a suspension of lithium niobate (LiNbO3) particles during freezing at nano and picosecond pum pulse durations.

Numerical Analysis of Ultrasonic Multiple Scattering for Fine Dust Number Density Estimation

open access: yesApplied Sciences, 2021
In this study, a method is presented for estimating the number density of fine dust particles (the number of particles per unit area) through numerical simulations of multiply scattered ultrasonic wavefields.

Numerical Study of Turbid Slab Optical Properties Reconstruction from Multiple Scattering Signals Using Time-Based Markov Chain Model

open access: yesApplied Sciences, 2021
The reconstruction of optical properties for opaque mediums is highly desired for medical, atmosphere and aerosol applications. However, the modeling and reconstruction process is highly related with multiple scattering phenomena, which elevates both the

Infrared singularities in multi-leg scattering amplitudes [PDF]

open access: yes, 2014
I discuss the state-of-the-art knowledge of long-distance singularities in multi-leg gauge-theory scattering amplitudes and report on an on-going calculation of the three-loop soft anomalous dimension through the renormalization of correlators of semi ...
