PROPAGATION OF LONG ELECTROMAGNETIC WAVES THROUGH ROCK

Abstract

A description is given of the propagation of long electromagnetic waves through rock, in continuation of previous studies on the VLF region. The theoretical bases of wave propagation are reviewed. Important results of comprehensive calculations are summarized and methods of measuring the propagation parameters, dielectric constant, and conductivity, are derived. The instruments used for conducting the measurements are described. Measurements in the near field and in the near field - far field transition zone as well as through ore beds are evaluated.
