An Improved Radiative Transfer Model for Polarimetric Backscattering from Agricultural Fields at C- and X-Bands [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2021
The first-order vector radiative transfer model (FVRTM) is modified mainly by examining the effects of leaf curvature of vegetation canopies, the higher-order multiple scattering among vegetation scattering particles, and the underlying-surface roughness

The Radiative Transfer Characteristics of the O2 Infrared Atmospheric Band in Limb-Viewing Geometry

open access: yesRemote Sensing, 2019
The O2(a1Δg) emission near 1.27 μm provides an important means to remotely sense the thermal characteristics, dynamical features, and compositional structures of the upper atmosphere because of its photochemistry and spectroscopic properties ...

Interpretation of Spectral LiDAR Backscattering off the Florida Coast

open access: yesRemote Sensing, 2021
A multispectral backscattering LiDAR (Light detection and range) system (hereafter Oculus) was integrated into a wave glider and used to estimate the scattering order (i.e., single vs multiple collisions) of LIDAR backscattering, the water inherent ...

Quantum multiple scattering [PDF]

open access: yesJournal of Modern Optics, 2009
The quest for Anderson localization of light is at the center of many experimental and the- oretical activities. Atomic vapors play a particular role in this research field, as they show a number of specific properties which makes them quite different from other materials used to look for Anderson localization.

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.

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.
