Dielectric Dispersive Properties of Subsurface Rock at a Buried Antenna Site.
Abstract
The electrical properties of rock specimens collected from the surface and subsurface of a buried antenna site were measured to provide information for calculating electromagnetic wave propagation constants for modeling and assaying antenna performance. The rock is aporhyolite exhibiting intense metasomatic alteration; the principal mineral constituents are epidote and sericite. The parameters (dielectric constant, dissipation factor, and effective conductivity) were measured in the range 10-100 kHz for both dry and moist conditions. These rock specimens when moist exhibited high dielectric constants and considerable dispersion at lower frequencies. (Author)
