The stationary electric field in the air: application to low frequency non-contact (electrostatic) resistivity prospecting

The problem of calculating the stationary electric field in the air accounting the dielectric permeability<br>over the conductive cross-section. The intensive effect of the measurement dipole elevation on the signal<br>level for certain types of models is demonstrated. The results obtained for the grounded current electrode are<br>applicable to the non-contact sources.
