Novel Fundamental Model for the Prediction of Multiply Scattered Generic Waves in Particulates

摘要

Fundamental models for accuratetly predicting multiple scattering of electromagnetic and acoustic waves through particulates have been in need for a long time. The lack of these models forces optical size analyzers to only accept highly diluted samples and impairs the performance of acoustic analyzers. After 20 years of R & D this vacuum has been filled with METAMODEL~(TM). This new multiple-scattering model is as fundamental as Mie and ECAH single-scattering models. Its generic validity resides in having modeled the interaction between the fields scattered by every particle, leading to generic stochastic field equations where the overlapping of all fields is contemplated regardless of their physical nature (viscous-inertial, thermal diffusion, electromagnetic, elastic, etc.). Its fundamentals are described, and validating data in concentrated dispersions are presented.
