Abstract
We consider the following electromagnetic sounding configuration: A time harmonic magnetic transmitter is placed on the surface of earth having a depth-dependent conductivity structure. The total magnetic field is measured at a fixed point with a finite number of frequencies. A numerical method is given for the recovery of the incident field directly by these measurements. The method is based on the use of the dispersion relation.
