We discuss the radiation of surface polaritons that are localized at a cylindrical interface that separates two media with different electromagnetic properties. Charged particles are considered as radiation sources. Different types of trajectories are studied, including rectilinear motion parallel to the axis of the dielectric cylinder and circular motion around or inside the cylinder. The...

As is known, the correct choice of the deviation function is very important in order to obtain a certain intensity, spectral and spatial distribution in the diffracted beams formed as a result of X-ray diffraction in deformed crystals. To describe the deviation function, it is sufficient to provide the dependence of the bending radius and interplanar distances of the reflecting atomic planes...

This study reports on the growth and comprehensive characterization of pure and L-Valine amino acid–modified α-LiIO₃ single crystals, with an emphasis on structural features and nonlinear optical properties. High-quality nonlinear optical (NLO) α-LiIO₃ crystals from pure aqueous solution and α-LiIO₃ crystals from an aqueous solution containing L-Valine amino acid (5 mol%) were grown using the...

The subject of the present study is L-nitroargininium 5-sulfosalicylate (L-NNA∙5-SSA) crystal. The thermal properties, vibrational spectra, UV-Vis transmittance spectrum, Vickers hardness and second harmonic generation activity were experimental studied. The crystal and molecular structure of crystal was determined by the single-crystal X-ray diffraction method. L-nitroarginine exists as a...

Pure and L-alanine (L-Ala) assisted lithium iodate (α-LiIO₃) single crystals were successfully grown from aqueous solution by the slow evaporation technique. The present work focuses on the comparative investigation of the mechanical and optical properties of pure and L-Ala-assisted α-LiIO₃ crystals, which are promising nonlinear optical materials for photonic and optoelectronic applications....
