Definition of the areas of space affecting results of the radio-wave method

It is known that in the insulator the area that has the main influence on the propagation of electromagnetic waves,is determined by the radius of the first Fresnel zone. But rocks are conductive medium. Examples of the results of calculations have been given, illustrating which area of the conducting space can have a significant impact on the re sults of the radio-wave method. In the given approach, each element A Vi of a conducting space, differing in electrical parameters from all other elements, is a source of a secondary electromagnetic field, similar to the field of an alternating electric dipole. The results of mathematical modeling can help to determine which area of the conducting medium under certain conditions has the main influence on the results of radio wave method. Simulation results can determine which region of the conductive medium has a major influence on the results of radio-wave method.
