The urgency of research of laws of wave processes in elastic environments with thermo mechanical effect is connected with necessity of the decision of theoretical and applied problems of geophysics, seismology, mechanics of composite materials etc. Connected equations of movement and the heat conductivity equation differ complexity and an abundance of physical-mechanical parameters. In this connection the section of mechanics of a deformable firm body, – thermo elasticity intensively develops. Within the limits of this direction, leaning against use of certain physical-mechanical properties anisotropic environments, the connected thermal and mechanical fields are studied. In given article, on the basis of a method matrizant, the decision of a problem of reflexion–refraction of waves on border of homogeneous anisotropic thermoelastic environments, for a case of matrixes of factors of 4th order is received.

In work harmoniously time-dependent decisions of equations Maxwell for anisotropic dielectric environments with magnetoelectric effect are considered. The structure of fundamental decisions of equations Maxwell (structure matrizer) is defined. On the basis of the received structure the equations of a dispersion of electromagnetic waves in periodically nonuniform environments with magnetoelectric effect are defined. Results of research of magnetoelectric effect can be applied, for example, in working out of new magnetoelectric gauges of a magnetic field and microwave frequency capacities. For such applications magnetoelectric materials are the most suitable thanks to a wide working temperature range.

Within the limits of this direction, leaning against use of certain physical-mechanical properties anisotropic environments, the connected thermal and mechanical fields are studied. In given article on the basis of a method matrizant, kinds of dependences of speeds and factors of the attenuation, the connected thermoelastic waves from frequency are defined; the quality graphs of thedependence of decay rates and attenuation coefficients of elastic and thermal waves (under small thermomechanical parameter) on the changes of temperature, heat conductivity tensor and frequency have been plotted.
