Analytical techniques for addressing forward and inverse problems of light scattering by irregularly shaped particles.
Understanding light scattering by nonspherical particles is crucial in modeling the transport of light in realistic structures such as biological tissues. We report the application of novel analytical approaches based on modified Wentzel-Kramers-Brillouin and equiphase-sphere methods that facilitate accurate characterization of light scattering by a wide range of irregularly shaped dielectric p...
متن کاملAnalysis of Irregularly Shaped Texture Regions
Four different texture classification methods (wavelet-based, co-occurrence matrices-based, 1D-histograms-based, and 1D Boolean model-based) are systematically compared and evaluated with respect to their performance in identifying textures from small and irregular samples. Two sets of 135 complex shape masks (symmetric and nonsymmetric) are created using Fourier shape descriptors, and used to ...
متن کاملEquiphase-sphere approximation for analysis of light scattering by arbitrarily shaped nonspherical particles.
We extend the previously proposed concept of equiphase sphere (EPS) to analyze light-scattering properties of arbitrarily shaped particles. Our analyses based on the Wentzel-Kramers-Brillouin technique and numerical studies based on the finite-difference time-domain method demonstrate that a wide range of irregularly shaped particles can be approximated as their equivalent equiphase ellipsoids ...
متن کاملLight scattering by aggregate particles
We have investigated scattering properties of aggregates, emphasizing the size of constituent monomers comparable with the wavelength of visible light, in order to model the scattering properties of cometary dust. This has differentiated our study from previous investigations of aggregates in which the size of the monomers was much smaller than the wavelength. For aggregates, the absorption cro...
متن کاملScattering of very light charged particles.
I advance arguments against the view that the Lee-Nauenberg-Kinoshita theorem is relevant in practice to the scattering of charged particles as their mass tends to zero. I also discuss the case of massive coloured particle scattering. Scattering cross-sections for reactions involving, in the initial state, a charged particle of mass m contain (in perturbation theory) ln m terms, which become la...
