Frequency Dependent Properties of Materials Containing a Distribution of Pores and/or Inclusions
The properties of a material are significantly changed by the presence of pores and/or inclusions. The dynamic behavior of such materials depends on the concentration, type, size and distribution of the pores and inclusions. Such materials behave effectively like lossy materials not only due to geometric dispersion or multiple scattering, but also real losses, if any, associated with the scatterers. A study of wave propagation in such materials is a convenient way to experimentally and theoretically predict the phase velocity and effective dynamic properties such as elastic moduli and dielectric constants.
