WebApr 12, 2024 · The Green’s function can be analytically expressed if the propagating medium is homogeneous. This allows for speeding up the inversion procedure, as the calcualtion of wavefield with the analytical solver is more efficient compared to the FDTD case. In addtion, the analytical solver allows us to not iterate over the whole computational domain. In statistics, homogeneity and its opposite, heterogeneity, arise in describing the properties of a dataset, or several datasets. They relate to the validity of the often convenient assumption that the statistical properties of any one part of an overall dataset are the same as any other part. In meta-analysis, which combines the data from several studies, homogeneity measures the differences or similarities between the several studies (see also Study heterogeneity).
