SOME APPLICATIONS OF FREQUENCY DOMAIN 2.5-D EM NUMERICAL MODELLING USING HED SOURCES

G. Pethő, L. Ficsór

Аннотация


Geophysical electromagnetic (EM) methods can be characterized with increasing role in applied geophysical research. Without modelling of EM fields a great deal of theoretical problems can not be solved and practical questions of measurements planning can not be answered. Assuming harmonic time dependent horizontal electric dipole (HED) sources parallel to the structural strike and perpendicular to it this paper deals with some applications and summarizes the results gained by 2.5-D frequency domain EM numerical modelling in the last years.
