Radiative Properties of Particulate Media: Mie Theory and Applications

This lecture covers the radiative properties of particulate media, focusing on Mie theory and its applications. The instructor begins by introducing the relative complex index of refraction and the characteristics of particle clouds, including isotropic and anisotropic scattering. The discussion progresses to the radiative properties of single spheres, detailing absorption, scattering, and extinction efficiency factors. The lecture emphasizes the significance of Mie theory in understanding light interaction with particles of various sizes and shapes. The instructor presents examples of how these principles apply to real-world scenarios, such as the analysis of soot in combustion products. The lecture also addresses the challenges of particle size distribution and the implications for radiative transfer in different media. By the end, the audience gains insights into the practical applications of these concepts in fields like renewable energy and environmental science, highlighting the importance of accurate modeling in predicting radiative behavior in particulate systems.
