Composite materials with carbon reinforced fibres now are widely applied in aircraft and space techniques. The influence of roughness to sensor signal is amplified and becomes comparable and in some cases more amplitude of a modulation pulse of a surface defect. Statistical and probability researches spectral and wavelet methods of identification have been(More)
In the past few years, much attention has been given to the development of neurophysiological methods of analyzing social interactions between subjects in response to natural stimuli presented in videos. This article describes a methodological approach for assessing similarities, and differences in how videos are perceived by different subjects based on(More)
Diffractive optical elements (polypropylene kinoform diffractive lenses, silicon binary diffractive lenses, and silicon beamsplitters) for the terahertz spectral range have been designed and characterized using high-power terahertz radiation of Novosibirsk free electron laser. The effect of an antireflection coating on the silicon elements was studied.
Results of experimental and theoretical studies of the capability of terahertz surface plasmons (SPs) to cross macroscopic air gaps in a substrate (or between substrates) with admissible losses are presented. SPs were launched with quasi-cw free-electron laser radiation with 130 μm wavelength (λ). We managed to detect SPs passing across gaps as wide as 100(More)
We present a new technique for direct conversion of thermal energy into coherent radiation. The near-surface layer of evaporated excited atoms of rare earth metals is proposed to be used as a converter. There is an inverted population in this layer. Operation principles of two level lasers on the transitions to the ground state using Eu are considered. The(More)
