| Zusammenfassung |
| Formulas for computing the Cartesian
components of the static (DC) fields of horizontal electric dipoles ( HEDs) and
vertical electric dipoles ( VEDs) located in the central zone of a three-layer
horizontally stratified medium are derived and presented in a summary form
suitable for immediate computation. Formulas are given for the electric and
magnetic field components in the upper and central regions. In the general case
the computation involves the summation of a convergent infinite series. For the
particular case of an infinitely thick central region (corresponding to the
two-layer problem), the analysis produces relatively simple closed-form
equations for the field components which are suitable for a 'hand calculation'.
Specimen calculations for dipoles in seawaters are included and the derived
results are compared with computations made using an ac model. |
