Time-Domain ElectroMagnetic (TDEM)

TDEM involves inducing electric and magnetic fields by transient pulses of electric current and measuring the subsequent decay response. The method uses coils on the ground for the transmission of the primary electrical field and the reception of the secondary magnetic field.

The investigation depth depends on the transmitting coil dimension on the ground, the intensity of the current and the conductivity of the layers.
