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)
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)
Temperature dependence of the transmission spectrum of one-dimensional multilayer photonic crystal with a liquid crystal defect layer has been studied. Dielectric multilayers have been fabricated by deposition of an alternating stack of SiO<sub>2</sub> and ZrO<sub>2</sub> layers on the glass substrate. Homeotropic layer of nematic liquid crystal 5CB is(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)
