 Standard linear solid Q model for attenuation and dispersion

The Standard Linear Solid (SLS) model is a viscoelastic model commonly used in the fields of material science, geophysics, and engineering to describe the mechanical behavior of materials under stress and strain. It is particularly useful for modeling phenomena such as attenuation (energy loss) and dispersion (variation of wave speed with frequency) in viscoelastic materials. ### Key Features of the Standard Linear Solid Model 1.
