The results of experimental investigations by the partial reflection radar of the electron density variations in the middle latitude ionospheric D-region during the morning solar terminator passage in the period of the magnetic storm dated the 7-11th of November, 2004, are presented. There was found the increase of the electron density more than 200% both in the period of the morning solar terminator passage and during tens min after this event. To explain such events a hypothesis concerning electron precipitations from the magnetosphere stimulated by the morning solar terminator is used. There were made estimations of the ionization rate. On the basis of the experimental data of electron density changes over the electron precipitation periods, corresponding fluxes were estimated, being p ≈ (0.6-8.8) 109 m-2 sec-1.

Processes of forming of the virtual cathode (VC) in the canular relativistic electron beam (REB) in the external magnetic field are analyzed numerically with the help of 3D electromagnetic model. It was discovered that dynamics of VC in the system is determined by the value of external magnetic field and by the features of physical processes in the REB.

A method of rapid determination of gas pressure value, which provides the most favorable conditions for microwave plasma chemical processing at low vacuum, is developed. The method is based on the characteristic property of microwave plasma materials processing which consists in pulsation nature of microwave discharge.

For MM and SubMM ranges, on the basis of high-quality Fabry-Perot resonator the original precision methods of investigation are discussed: atmospheric absorption, including continuum absorption; radiant reflectance of metals; refraction index and loss tangent of dielectrics, including films and liquids. The methods of measurement are absolute ones and self“calibrated” that means it is not necessary to use the prior information. Concrete values are calculated on the basis of measuring of adjustment frequency and line width of empty and loaded resonator. The temperature range is 80 K-900 K for investigation of condensed medium; for atmospheric - from -30 C up to +60 C and at humidity - 0%-80%. The measurement results of latest polymeric materials are presented.

In the present report the solution of the problem of electrical current distribution along thin radial impedance monopole, located on perfectly conducting sphere, has been found in pure electrodynamical statement. The approximate analytical solution of the integral equation has been obtained by the method of iterations both for the case of excitation of the monopole by a δ-generator of voltage, located at finite distance over the spherical scatterer, and at the excitation of the monopole at its basis.
