Light scattering in participating media and translucent materials is typically modeled using the radiative transfer theory. Under assumption of independent between particles, it utilizes several bulk parameters to statistically characterize light-matter interactions at macroscale. To calculate these based on microscale material properties, Lorenz-Mie theory has been considered gold standard. In...

In optical particle characterisation and aerosol science today light scattering simulations are regarded as an indispensable tool to develop new particle characterisation techniques or in solving inverse light scattering problems. Mie scattering and related computational methods have evolved rapidly during the past decade such that scattering computations for spherical scatterers a few order of...

Mie theory offers an exact solution to the problem of scattering of sunlight by spherical drops of water. Until recently, most applications of Mie theory to scattering of light were restricted to a single wavelength. Mie theory can now be used on modern personal computers to produce full-color simulations of atmospheric optical effects, such as rainbows, coronas, and glories. Comparison of such...

Despite the quantum nature of the process, collective scattering by dense cold samples of two-level atoms can be interpreted classically describing the sample as a macroscopic object with a complex refractive index. We demonstrate that resonances in Mie theory can be easily observable in the cooperative scattering by tuning the frequency of the incident laser field or the atomic number. The sol...

Electromagnetic scattering by a homogeneous, isotropic sphere is commonly referred to as Mie theory, although Gustav Mie (1868–1957) was not the first to formulate this electromagnetic scattering problem. Before him Alfred Clebsch (1833–72), solving the elastic point source scattering problem of a perfectly rigid sphere using potential functions [1], and Ludvig Lorenz (1829–91) [3, 2] contribut...

Narrow angle light scattering measurements were made for various sizes of spherical particles suspended in water. These were compared to calculated theoretical scattering values as derived from the theory of Mie (1908). Through measurements with different particle concentrations at angles between 0.2 degrees and 0.7 degrees the effect of the unscattered main beam light was removed. Results agre...

PURPOSE Monte Carlo methods based on the Boltzmann transport equation (BTE) have previously been used to model light transport in powdered-phosphor scintillator screens. Physically motivated guesses or, alternatively, the complexities of Mie theory have been used by some authors to provide the necessary inputs of transport parameters. The purpose of Part II of this work is to: (i) validate pred...
