The Time Domain Electromagnetic Transient (TDEM) method aims to determine the electrical resistivity of subsurface materials through the decay of the secondary magnetic field due to the variation of the temporal flux of the primary magnetic, initially induced by an artificial current flux. The TDEM method is a valuable tool in geophysical studies and subsurface exploration for several reasons:
- It can penetrate to great depths underground. This makes it possible to investigate targets located at great depths, such as mineral deposits, deep aquifers, and oil and gas reservoirs.
- It is highly sensitive to the electrical conductivity of the subsoil. This makes it ideal for identifying targets that have significant conductivity contrasts, such as mineral deposits, groundwater, contaminants, or geological structures.
- It is a non-destructive and non-invasive method, meaning that it does not require excavations or disturbances at the study site.
