Absorption by Particle Edges and Asperities

Abstract

Measurements of infrared emittance from powders indicate that edges and other asperities on the particles cause enhanced absorption. A theory of the particle phase function, in which the asperities are represented by a surface distribution of induced dipoles, was able to fit the experimental results and to predict the outcome of further experiments correctly.
