Abstract The possibility of using the information parameter of the depolarization wave passing through a medium with a pronounced anisotropy of dielectric properties, for medical diagnostics is considered. Structuring is a distinctive ability of biological tissue due to the presence of a large number of thin fibers forming a regular system. A model problem is a medium with anisotropic properties in a grid of resistive threads. The optimal frequency of measurements, on which providing the greatest attenuation matching and maximum cross-polarization component, and the depolarization also reaches a maximum is available. Transmittance at cross-polarization increases with increasing conductivity filaments on an agreed same polarization as generally decreases with the level of the transmitted field. Phase ramp of the transmission coefficients with increasing frequency can be regarded as diagnostic information about the resistivity of the biological tissue. Changes in energy and phase characteristics of the transmitted electromagnetic waves are agreed, and the cross polarizations makes use of the results of the measurements for extracting information about deviations from the typical properties biological tissue.
