Processes of sol–gel technology of template synthesis of 3d-element metal macrocyclic complexes that occurs in thin films of metalhexacyanoferrate(II) gelatin-immobilized matrix implants under their contact with water solutions containing various (N,O,S)-donor atomic and (C=O) containing organic compounds, have been discussed. It was noted that, in a series of cases, sol–gel technology of template synthesis in the given specific conditions allows to realize such metal macrocyclic complexes formation processes that are not typical at the complexing in solutions or solid phase. © 2014, Springer Science+Business Media New York.

In the paper an approach to improve diffraction efficiency of a transmission concave holographic grating for a flat-field spectrograph is presented. The proposed method is based on numerical optimization of a merit function. Each iteration of the procedure includes definition of the grating recording parameters and the spectrum position from conditions of aberration correction, estimation of the diffraction efficiency by means of the Kogelnik coupled-wave theory equations, and checking boundary conditions. It's shown on a certain example that the technique allows to obtain high spectral resolution and increase the diffraction efficiency. Modeling results and comparison with accurate RCWA computation are provided as well. © 2013 SPIE.

A model of a multivelocity multitemperature polydisperse gas suspension has been constructed with account taken of coagulation. Calculations of the dynamics of an aerosol of a polydisperse composition in an acoustic resonator have been done and the derived regularities have been described. A system of Navier–Stokes equations for a compressible heat-conducting gas was used to describe the motion of a carrier medium. The dynamics of dispersed fractions is described by a system of equations including continuity, momentum, and internal-energy equations. The equations of motion of the carrier medium and dispersed fractions have been written with account of the interphase exchange of momentum and energy. The Lagrangian model has been used to describe the process of coagulation. The change in the dispersity of the gas suspension in the nonlinear field of an acoustic resonator has been analyzed. © 2015 Springer Science+Business Media New York

IEEE Transactions on Antennas and Propagation | Year: 2015

This communication studies the phase pattern of an antenna, with its phase front being significantly different from a sphere. Therefore, the concept of local phase center (LPC) has been used. Two algorithms of LPC hodograph computation are presented and verified by comparison with analytical results. Even in the simplest case of two sources, a curve of the LPC hodograph may be curious and hardly predictable. This is particularly true if a special phase pattern arises, e.g., as a result of the desired amplitude pattern synthesis. Two examples with sector and secant patterns are studied and the relevant LPC-hodographs are demonstrated. All calculations prove that the LPC is unexpectedly well defined. © 1963-2012 IEEE.
