Summary

Description
English: Scattering efficiency computed from Mie theory for a sphere of refractive index (approximately that of water in the red) as a function of the size parameter. is defined as where a is the radius of the sphere and is the scattering cross section. The size parameter x is defined as , where N is the refractive index of the surrounding medium and λ is the wavelength in vacuum. The inset shows the same results in log scale, zooming in the small x region and evidencing the law of Rayleigh scattering. These results have been obtained by using the MiePlot program, with post treatment under Octave and Inkscape.
Français : Efficacité de diffusion calculée d'après la théorie de Mie pour une sphère d'indice de réfraction (approximativement égal à celui de l'eau dans le rouge) en fonction du paramètre de taille. est défini par , où a est le rayon de la sphère et est la section efficace de diffusion. Le paramètre de taille est défini par , où N est l'indice de réfraction du milieu entourant la sphère et λ est la longueur d'onde dans le vide. L'insert montre les mêmes résultats en échelle log, ce qui permet de zoomer sur la petites valeurs de x et de mettre en évidence la loi correspondant à la diffusion de Rayleigh. Ces résultats ont été obtenus en utilisant le programme MiePlot avec un post traitement sous Octave et Inkscape.
