30 Jan 1998TL;DR: In this article, a light scattering technique, preferably using laser light, is employed to monitor particle concentrations within the processing chamber of a plasma-based substrate processing system, where particle concentrations are increased in the light field of the sensor by creating an electric or magnetic field to concentrate the particles suspended therein.
Abstract: A method and apparatus for increasing the sensitivity of an in situ particle monitor. A light scattering technique, preferably using laser light, is employed to monitor particle concentrations within the processing chamber of a plasma-based substrate processing system. Particle concentrations are increased in the light field of the sensor by creating an electric or magnetic field in the processing chamber to concentrate the particles suspended therein.

TL;DR: An efficient calculation method for light scattering due to clouds taking into account both multiple scattering and sky light, and the modeling of clouds is described.
Abstract: Methods to display realistic clouds are proposed To display realistic images, a precise shading model is required: two components should be considered One is multiple scattering due to particles in clouds, and the other factor to be considered is sky light For the former, the calculation of cloud intensities has been assumed to be complex due to strong forward scattering However, this paper proposes an efficient calculation method using these scattering characteristics in a positive way The latter is a very significant factor when sky light is rather stronger than direct sunlight, such as at sunset/sunrise, even though sky light has been ignored in previous methods This paper describes an efficient calculation method for light scattering due to clouds taking into account both multiple scattering and sky light, and the modeling of clouds CR Categories and Subject Descriptors:

TL;DR: A remarkable enhancement of Raman scattering is achieved by TiO2 shell-based spherical resonators in the absence of plasmonic enhancers and can be exploited to fabricate a new generation of self-diagnostic, recyclable SERS-active substrates.
Abstract: A remarkable enhancement of Raman scattering is achieved by TiO2 shell-based spherical resonators in the absence of plasmonic enhancers. This effect is ascribed to the synergistic combination of high refractive index of the shell layer, multiple light scattering through the spheres, and related geometrical factors and can be exploited to fabricate a new generation of self-diagnostic, recyclable SERS-active substrates.

TL;DR: In this article, it was shown that if the grains in composite media are large enough to give rise to magnetic dipole and higher-order multipole radiation, then the effective permeability of the composite medium cannot be taken to be that of free space even if the gra...
Abstract: Effective-medium theories yield effective dielectric functions (or, equivalently, refractive indices) of composite media. Such theories have been formulated that go beyond the Maxwell-Garnett and Bruggeman theories, which art restricted to media composed of grains much smaller than the wavelength. These extended effective-medium theories do not, however, yield effective dielectric functions that can be used for the same purposes for which we unhesitatingly use the dielectric functions of substances such as pure water and pure ice (e.g., reflection and transmission by smooth interfaces; absorption and scattering by particles). Extended dielectric functions can lead to unphysical results; for example, absorption in composite media with nonabsorbing components. Moreover, if the grains in composite media are large enough to give rise to magnetic dipole and higher-order multipole radiation, then the effective permeability of the composite medium cannot be taken to be that of free space even if the gra...

TL;DR: In this paper, the scattering of light by small particles is studied and the authors propose a method for the detection of small particles in the light scattering of a single photon. But this method requires a large number of particles.
