 The Kolsky basic model and modified model for attenuation and dispersion

The Kolsky models are theoretical frameworks used to describe wave propagation in materials, particularly focusing on the phenomena of attenuation and dispersion. These models stem from work done by A. Kolsky in the mid-20th century and are typically applied in material science, geophysics, and engineering disciplines. Here’s a brief overview of both the basic and modified Kolsky models: ### Kolsky Basic Model 1.
