STUDY AND APPLICATION OF NORMAL FIELD OF EM CHARGE METHOD OF HORIZONTAL ELECTRIC DIPOLES

In this paper,the formulas of components of EM field produced by horizontal electric dipoles in underground half space with low resistance layer are given. And theoretical curves of normal field have been computed and analyzed. Prac- tice data have been explained used the results. The results show that the magnetic field are stable and the effects of low resis- tance layer are small in low frequency.
