Equivalence between mechanical and dielectric models

The lectures on fractional models concentrated on mechanical models. But as some of you work with radar, it should be noted that these models are analogous to models for electromagnetic wave propagation in complex media like soil (ground-penetrating radar) and human tissue (biomedical radar).

• The mechanical Zener model = the Debye model 
• The fractional Zener model = the Cole-Cole model 
• The multiple relaxation model = sum of several Debye models with different time constants 

The mechanical models are outlined in Attenuation part 2.
