摘要:
AbstractThe transient fields from a finite horizontal loop excited by a half sine wave current pulse have been computed numerically for a particular source receiver configuration at a height of 100 meters above a layered ground. The amplitude of the vertical component of the magnetic field has been chosen for the interpretation. Curves of apparent conductivity vs. time, plotted during the off‐time of the signal, show that layering is easily resolved, that resonance effects are present and that polarization effects are detectable for certain types of polarizatio
