O nacistikano Samudaripen e Rromenqëro p-i Belarusìa
No full textThe article deals with the genocide of Roma on the territory of Belarus in the time of the Second World War. The author, referring to the documents of the State Archive of the Russian Federation, other source materials and interviews conducted with the eyewitnesses, analyzes particular cases of the extermination of Roma. He has also determined the minimal figure of the Roma murdered during the World War II in Belarus as 1,000 victims. This figure is supported by the existing documentary evidence and thus reliable.O artìklo azbal o nacistikano Samudaripen e Rromenqëro p-i Belarusìa.

Research of a possibility of resonator diagnostics of thin filamentary objects in a low part of the terahertz frequency band
No full textThe method of excitement of the open resonator by the narrow slot on a reflector formed by the waveguide with the highest modes transmitted was experimentally approved. The spectra of such resonator in the range of the frequencies of 85 GHz - 110 GHz were received. It is shown that modes with azimuthal variations of the fleld were most effectively exited. Transformations of spectra by thin dielectric cylinders were researched. A number of parameters of the open resonator, effective in schemes of resonator diagnostics of fllamentary objects with small own losses were found

Local quasioptical resonator diagnostics of semiconductor wafers
No full textThe method of measurement of reflection coefficient behind an orifice in one of reflectors of the quasioptical open resonator is considered. According to the applied mathematical model, the method has the restriction which is consist in use of a short-wave approximation for the orifice size (it dimension is much more than a wavelength). For evaluation of limits of applicability of this method the experimental setup in the threecentimetric range of wavelengths consist of the quasioptical open resonator and the system of positioning of the measuring probe is created. By the experimental study of distribution of fields behind an orifice in the reflector of the open resonator it is found that the method, except restriction of mathematical model, has also restrictions, due to the wave’s interference, reflected from edges of this orifice. It causes a deviation from the uniform amplitude distribution of the field in an opening that can lead to increase in an error of a reflection coefficient measuring. It is also shown that by decrease of the sizes of an orifice formation of a bunch with small divergence, but with significantly more expressed distribution of the field localized about a bunch axis in an aperture is possible. It can be used for diagnostics of inhomogeneity of samples with higher locality
