## 1 Introduction
Various methods exist to establish the relationship between microstructure and porous material properties, such as those described in [6; 7; 8; 9; 10; 11; 12] for elastic deformation and those for homogenization [13]. The novelty of this scientific approach lies in the improvement of methods for calculating effective parameters and studying the macro anisotropic characteristics of rocks through the approximation of real geological media with layered bianisotropic media. Such approximations of matrices incorporate inclusions with various shapes and different properties [13]. Somehow, petrological and cross property relations are also included, e.g., the general singular approximation (GSA) [6]. Here, bianisotropic media refers to media characterized by a multitude of parameters contained in four permeability tensors. We here and onward in all the text consider an element network model (capillarity system) in which the omega shape (\(\Omega\)) inclusion serves as a structural element of the bianisotropic media. This provides a magnetoelectric relation, where the electric and magnetic moments induced in the inclusion by the electromagnetic field are perpendicular to each other. When two \(\Omega\) inclusions are positioned in a plane with mutually perpendicular straight sections, a \"cap\" is formed, which acts as a structural element of uniaxial bianisotropic media. We define an effective electromagnetic parameter of a media as a parameter obtained through the homogenization method of macroscopic Maxwell equations [14; 15] applied to its function on spatial coordinates over a physically small finite volume. The idea is significant, as homogenization theory was employed for the analysis of periodic micro-structure contact stress in compressed granite. In general, methods of electromagnetic monitoring of modern geodynamic processes can be categorized as active and passive. Passive methods involve passive registration of the Earth's own electromagnetic radiation and are associated with irreversible deformations of rock during crack-forming processes when the stress-strain state changes. In such cases, sources of endogenous electromagnetic fields are generated, which are the focus of passive electromagnetic monitoring [16]. Accordingly, we respect the following principle: with a given observation system, either generally inhomogeneous media or macroscopic anisotropic parameters of the geoelectric media are considered. For each electromagnetic monitoring point, a geoelectric model was preliminarily built to depths of about 40 km (based on the MTS profile), which shows the distribution of geoelectric inhomogeneities, i.e., objects with different electrical conductivity in the geological environment. We could thus monitor the position of objects with different electrical conductivity over time. The object of study in electromagnetic monitoring of modern geodynamic processes is changes in the electromagnetic parameters of geological media, which are associated with both reversible and irreversible deformations of rock under the influence of external factors [17]. These factors include lunar-solar tides, fluid dynamics, tectonic processes, and anthropogenic impacts on the lithosphere, leading to changes in the stress-strain state of the geological media [18]. Observation systems with controlled sources of electromagnetic fields are employed, including methods of magnetotelluric sounding of the Earth [19; 20; 21], which provides information on the physicoelectric (electromagnetic, magnetochemical, physicochemical, etc.) parameters of the lithosphere. These parameters are integral and macroscopic in nature. The lunar-solar connection with Earth's electromagnetic parameters has been established [22; 23; 24; 25]. This study aims to investigate the changes in macroscopic physicoelectric properties of rocks associated with variations in their internal microstructure.
