Using a three-layer 1-D model and a 3-D model the authors have demonstrated that GPR (ground penetrating radar) waves are greatly attenuated in dispersive media because dispersion results in increased effective conductivities and reduced effective permittivities. This can be further illustrated by using equivalent conductivities and equivalent permittivities that are the effective conductivities and effective permittivities of dispersive models at the principal GPR frequency. Dispersive model responses are very similar to their nondispersive equivalents.
