Scattering database for spheroidal particles.
We present a database containing light scattering quantities of randomly oriented dielectric spheroidal particles in the resonance region. The database has been generated by using a thoroughly tested T-matrix method implementation. The data possess a defined accuracy so that they can be used as benchmarks for electromagnetic and light scattering computations of spheroids. Within its parameter r...
متن کاملRay scattering model for spherical transparent particles.
We propose a model for the reflectance of a particle medium made of identical, large, spherical, and absorbing particles in a clear binder. A 3D geometrical description of light scattering is developed by relying on the laws of geometrical optics. The amount of light backscattered by a single particle is determined as a function of its absorbance and refractive index. Then, we consider a set of...
متن کاملScattering and Polarization Properties of the Non-spherical Particles
The albedo and dichroic polarization of spheroidal particles are studied. For the description of the phase function two asymmetry parameters g|| and g⊥ characterizing the anisotropy in forward/backward and left/right directions are introduced and calculated. The consideration is based on the solution to the light scattering problem by the Separation of Variables Method (Voshchinnikov and Farafo...
متن کاملLight Scattering by Marine Particles: Modeling with Non-spherical Shapes
The inherent optical properties (IOPs) of marine particles are most-often modeled and interpreted by assuming that they are homogeneous spheres. Although this approach has been fruitful, the next logical step in modeling the IOPs of marine particles is to abandon the normally-employed spherical approximation and use more realistic idealizations of their shape. The advent of computer codes capab...
متن کاملModelling Polsar Scattering Signatures at Long Wavelengths of Glacier Ice Volumes
The crucial role of cryosphere for understanding the global climate change has been widely recognized in recent decades [1]. Glaciers and ice sheets are the main components of the cryosphere and constitute the basic reservoir of fresh water for high-latitudes and many densely populated areas at mid and low latitudes. The need of information on large scale and the inaccessibility of polar region...
