Modeling power law absorption and dispersion in viscoelastic solids using a split-field and the fractional Laplacian.
The absorption of compressional and shear waves
in viscoelastic solids is modeled using a split-field and the fractional Laplacian. The fractional Laplacian is used to model the dispersion of the waves in the viscoelastic medium. The fractional Laplacian is a generalization of the standard Laplacian operator, which is used to model the dispersion of waves in elastic solids
