the color recognizing computer adapter for the prompt determination of sugar content in the blood of patient with the native test-strips is developed;

the possibility of negative longitudinal shift of confined beams formed by flexural waves, by Langmuir waves in isotropic collisionless plasma, by electromagnetic waves, acoustic waves is predicted;

surface optical effects caused by the violation of the translational symmetry at the boundaries of one-, two-, and three-dimensional dielectric media are theoretically investigated;

in co-operation with German scientists the rigorous microscopic quantum theory of the interaction of ultracold Bose and Fermi gases with electromagnetic field of vacuum and laser photons has been developed. Starting from the first principles of QED the general system of Maxwell-Bloch equations has been derived, which can be used for the description of various linear and nonlinear phenomena in atom optics.
