Abstract :
The effect of the frequency dependence of the conductivity and permittivity of rock for pulse transmission is considered. These high-frequency dispersive effects appear to play a major role in determining the transient response of the medium. A quantitative understanding is achieved by adopting a dispersion model that consists of multiple Debye relaxation processes. It is shown that the results differ significantly from earlier transient calculations that assume frequency independent permittivities and conductivities.
