Abstract :
The method of 3D harmonic electromagnetic fields modeling for solving tasks of magneto-telluric sounding (MTS) has been developed and realized. The scheme with field separation to normal and anomalous components has been used for the modeling of natural electromagnetic Earth field. Nonregular parallelepiped and hexahedral elements have been used for the finite element approximation. For acceleration of calculation of the field from local near-surface heterogeneities the multilevel scheme of 3D field separation has been developed.
