The radiation from a vertical electric dipole located in the upper anisotropic layer of a stratified conductive earth is analysed in detail. The variations of the near fields in the anisotropic medium and outside zone have an appreciable dependence on the anisotropy factor in the neighbourhood of the dipole. However, the amplitude gradients (with respect to the numerical distance) remain almost uniform for varying coefficients of anisotropy and for the conductivity contrast between the isotropic lower half-space and the longitudinal conductivity of the upper anisotropic conducting layer. The results have applications in underground communications and submarine detection.
