【Abstract】 In this paper, by numerical calculation based on Mie scattering and anomalous diffraction theories, we compared and analysed the Mie scattering and anomalous diffraction of spheres with refractue index near 1 in detail, and present a criterion of spheres with refractive index near 1 when anomalous diffraction theory can be used to replace Mie scattering theory.更多还原
