Optical biosensor based on a photonic crystal with a defective layer designed to determine the concentration of SARS-CoV-2 in water
I. M. Efimov, N. A. Vanyushkin, A. H. Gevorgyan +1
We propose a new optical biosensor based on a photonic crystal with a defect layer, which can determine the SARS-CoV-2 concentration in water by the defect mode shift. Two models o…
Scattering of a plane wave by an inhomogeneous 1D dielectric layer with gradient refractive index
N. A. Vanyushkin, A. H. Gevorgyan, S. S. Golik
We propose a new method for calculating reflection and transmission coefficients for an arbitrarily polarized electromagnetic plane wave incident on a one-dimensional dielectric me…
Magnetically induced transmission/absorption in chiral liquid crystals
A. H. Gevorgyan
We report the discovery, theoretically, of new effects, namely, the effects of magnetically induced transparency/absorption. The effects are observed in a magnetically active helic…
Effect of Anisotropy on Defect Mode Peculiariries in Chiral Liquid Crystals
A. H. Gevorgyan, K. B. Oganesyan
The effect of anisotropy on defect mode peculiarities in cholesteric liquid crystals is investigated. The problem is solved by Ambartsumians layer addition modified method. Two cas…
The cross sections for inelastic neutron scattering and radiative capture in the field of a light wave
E. A. Ayryan, A. H. Gevorgyan, I. V. Dovgan +1
The mixing of the levels of a compound nucleus in the field of a high-intensity light wave is considered. The cross sections for inelastic neutron scattering and radiative capture…
Absorption and Emission Dependences on Defect in CLC
A. H. Gevorgyan, K. B. Oganesyan, Yu. V. Rostovtsev +2
The influence of the defect position on absorption and emission in the cholesteric liquid crystal with an isotropic defect inside is studied. It is shown that for non-diffracting c…
