the coordinate transformation method. The role of real and virtual foci in the mechanism of focusing by a multilayered lens
is considered.

Methods of physical and numerical experiments are used to investigate formation of quantum dissipative silver nanostructures
on polypropylene microfibrous condensed-state carriers under two-stage activation by UV- and microwave radiation. For these
two nanoprocessing stages, two different mechanisms of quantum activated silver nanoparticle relaxation are suggested, including
dissipation of their energy into the polymeric matrix through the exciton femtosecond and phonon picosecond channels. A comparison
of the results of mathematical modeling and physical experiments testifies to the adequacy of these models to the physical
processes of self-assembly and self-organization of polymeric biomimetic fibrous material modified by silver nanoparticles.

An asymptotic formula is constructed for the dependence of the serial number of harmonic on the relativistic factor for circularly
polarized synchrotron radiation in the upper half-plane. Numerical values of particle velocities at which the maximum of synchrotron
radiation intensity is transferred from one harmonic to another are obtained.

A relationship determining the magnitude of magnetostriction in a given direction and its constant along the [100] easy direction
are obtained with the use of the thermodynamic potential for a weak easy-plane ferromagnetic material based on calculations
of the spontaneous components of the crystal strain tensor in terms of its elastic and magnetoelastic constants. An expression
determining the specific compressibility of the crystal through its elastic constants is derived.

Using a technological system proposed by the authors, a combined process is developed for formation of stratified-gradient
surface layers and multicomponent coatings. It is implemented under the conditions of a combined serial-parallel operation
of a hot-cathode gas plasma generator and a duomagnetron with two targets and two electric-arc evaporators. The extended functional
potential is ensured by using advanced multi-element and multi-phase cathode targets made of borides, carbides, silicides,
and sulfides of metals produced by the SHS-process followed by their immediate compaction. The variations in composition,
structure, and physicomechanical properties in the cross-section of the stratified-gradient surface layers and coating is
provided by a predetermined alternating replacement of the sputtered cathode targets of the plasma sources, the plasma flow
intensity ratios, and variation in the particle energy incident on the substrate, which is determined by the accelerating
voltage on the substrate.

The effect of various physical factors (chemical composition, temperature, and thermal treatment) on the macroscopic properties
of Co–SiO₂ film composites produced by ion-plasma sputtering of mosaic targets has been investigated. The microstructure parameters
have been estimated indirectly by analyzing the magnetization curves and the temperature dependence of magnetization. It has
been concluded that the model of homogeneous noninteracting superparamagnetic particles of hexagonal Co is applicable for
describing the magnetic properties of the film composites under study over a rather wide range of compositions.

A first-principle procedure is proposed to determine the Gruneisen parameter for a crystal by calculating the external pressure
and the vibration spectrum as functions of the volume of a unit cell. In the gradient approximation of the electron density
functional theory, on the basis of a linear combination of atomic orbitals, the elastic and the thermodynamic Gruneisen parameters
of silver azide, which decrease with volume (with increasing pressure), are calculated with the use of the CRYSTAL09 code.
The equilibrium values of the parameter γ₀ for various cold equations of state of crystals and for the thermodynamic models used are, respectively, ~2.3 and 1.6.

The influence of a graded-band near-boundary region with a linear change in the energy gap and potential step on the effective
surface recombination rate is considered for heterostructures based on p-cadmiummercury-tellurium. It is shown that for decreasing the surface recombination rate it is necessary, in the initial
stage, that the energy-gap width increased more slowly as compared with its increase according to the linear law.
