Webb25 apr. 2024 · As one of the most popular empirical dispersion models, the Debye model is commonly used to describe the electrical dispersion behaviors of a homogeneous lossy media. Debye model uses some empirical coefficients to control the shape and position of the spectroscopy curves. It can fit most of the data from experiments ( Shen, 1987 14. WebbA mathematical connexion between random particle paths, as described by the relative dispersionmodel, and concentrations, is provided by the statistical theory of dispersion. From the Cambridge English Corpus Shawbury wind observations have been used in this paper as a prime source of data for input to the dispersionmodel.
WebbIn this study, effects of the long-range interatomic and interlayer interactions on the dispersion of acoustic waves by multilayer graphene are investigated. A hybrid model that accounts for the long-range interatomic and interlayer interactions is developed. In the context of this model, the interatomic interactions are modeled based on the general …
