| Abstract: | The low-frequency characteristics and the problem of penetrating high resistance shielding layer for verticle magnetic dipole parametric depth sounding are investigated theoretically in some detail. The relevant approximate formulas are derived, with the requirements for their application specified. In order to check the correctness of these approximate formulas as well as to get some idea about the magnitude of errors, we compare them for some examples with the exact results calculated through an electronic computer. |
