- A birefringence phenomenon for electromagnetic and a similar phenomenon for shear waves;
- Pleochroism phenomena for electromagnetic and linear acoustic anisotropic absorption for shear waves;
- Optic activity (electromagnetic waves) and rotating polarization vector in some media (shear waves);
- An increase of an ellipticity degree of polarized (electromagnetic and shear acoustic) waves during their propagation in a randomly-heterogeneous medium.
It is supposed that the electromagnetic and gravitational influence of one physical body on the other is realized by means of the ethereal medium. Assumption of the postulates of both special theory of relativity and general theory of relativity has not allowed getting a non-contradictory physical model of the universe. The following idea of the universe is proposed. Space embraces everything. It is non-deformable, three-dimensional, Euclidean. The visible space is filled by with ethereal medium. The physical model of the ethereal medium consists of two equal, but opposite in sign, types of particles. The particles are strongly attracted together forming a homogeneous space. A magnetic field is the consequence of torsion; shear deformations of the ethereal medium. The ethereal medium has a certain electromagnetic density and elasticity. Physical bodies (elementary particles, gases, liquids, solid bodies, plasma et al.) take place in the space and ethereal medium. Dynamical processes in the ethereal medium and movements of physical bodies may be fixed in time. Time is local, irreversible, one-dimensional, unilateral, - from the past to the future.
