“…The second simpler method is to construct a wave equation for the single non-zero component of the magnetic field ϕ H . This method was carried out by solving the wave equation by the method of separating variables in article [13] . For the convenience of references, we present the results of calculations for non-zero components of the electromagnetic field in a continuous medium, expressed through the given surface impedance (K is a constant that does not play a role in determining the impedance):…”

Impedance is the basic concept and quantity when measuring an electromagnetic field near the earth’s surface. It is shown how the antennas of the IPI device are oriented, and how the coordinate system is set. It is established why the phase difference of the electromagnetic field component is limited to the limits from zero to minus ninety degrees. The introduction of the basic electrophysical characteristics of a continuous medium - dielectric constant and electrical conductivity - is considered. For a homogeneous medium, the dependence of impedance on electrophysical quantities is given. The Riccati equation for impedance is given. Not only the horizontal arrangement of the electrical cable is considered, but also the vertical one. The latter allows you to explore the electrical parameters of the media.
