Gold nanocrystals exhibit unique optical properties in enhanced light absorption and scattering owing to their extremely large scattering/absorption crosssections and large electric field enhancements generated by localized surface plasmon resonance. In this work, the optical properties of gold nanospheres with diameters of 60 nm and 200 nm with remarkable uniformity in size were studied both ...

We study the inverse boundary problem for nonlinear two photon absorption radiative transport equation. show that coefficients and scattering coefficient can be uniquely determined from albedo operator. If is absent, we do not require smallness of incoming source, reconstruction explicit.

[1] Aerosol light absorption can be intense close to local sources such as wildland and oil fires, with smoke that disperses into the boundary layer and, with enough lift, into the upper atmosphere where it may be transported around the globe. Filter-based methods such as the Particle Soot Absorption Photometer (PSAP) are most commonly used to quantify aerosol light absorption aloft. This paper...

Terahertz (THz) anisotropic absorption in graphene could be significantly modified upon applying a static magnetic field on its ultra-fast 2D Dirac electrons. In general, by deriving the generalized Fresnel coefficients for monolayer under applied field, relatively high incoming linearly polarized light with specific scattering angles achieved. We also prove that of corresponds well to surface ...

Light extinction by aerosols is due to scattering and absorption. The anthropogenic contribution is generally dominated by light scattering by sulfate particles and light absorption by elemental carbon. While real-time, in situ instrumentation for the measurement of ambient light scattering exists and is widely used (i.e., nephelometers), no such instrumentation is currently in use for the sens...

salinity stress results to decreasing leaf area index (lai) and light absorption in plant leading in yield decrease. in order to study effect of salinity and iron sulphate on lai, absorbed light percentage and yield of sunflower (euroflor cultivar), an experiment was carried out as split plot based on complete randomized block design with four replications in the research field of university of...
