This study is based on new soliton solutions of the system of equations for the ion sound wave under the action of the ponderomotive force due to high-frequency field and for the Langmuir wave. The generalized Kudryashov method (GKM), which is one of the ... see more

It is shown, the modulation instability processes of long-wave Langmuir oscillation in hot and cold plasmas are possessed such a symmetry and mechanism of short-wave oscillation excitation. The maximum of the growth rate of the instability in cold plasma ... see more

The paper considers the instability of intense Langmuir oscillations in nonisothermal (Zakharov's model) and cold (Silin's model) 1D plasma. The main attention is paid to the formation of plasma density caverns in the hydrodynamic and hybrid (electrons ar... see more

The excitation of wake waves by the electron bunch in an isotropic plasma-dielectric waveguide is studied. It is shown that the excited field consists of two components: the field of the Langmuir wave and the field of eigenmodes of a dielectric waveguide.... see more

Nonlinear regimes of one-dimensional parametric instabilities of long-wave plasma waves are considered for the cases when the average plasma field energy density is less (Zakharov’s model) or greater (Silin’s model) than the plasma thermal energy. Th... see more

We report the preparation and optical characterization of Langmuir and Langmuir-Blodgett (LB) films of mesoporous silica coated gold nanorods with three different shell thicknesses. When measured in solution, the extinction of the particles in theshort wa... see more

Various models for description of the modulation instability of intensive Langmuir oscillations in plasma in one–dimensional representation are discussed. It is noted that the kinetic damping on the electrons can violate the conditions of the modulat... see more

New theoretical description of well-known physical phenomena are announced. 1. The description of wave interaction in plasma in terms of spontaneous and stimulated processes is discussed. Such a description is not only attractive from the methodologi... see more

We optimized the optical setup originally designed for the photoluminescence measurements in the spectral range 400?1100 nm. New design extends the spectral range into the near infrared region 900?1700 nm and allows the colloidal solutions measurements in... see more
