Engineering Applications of Computational Fluid Mechanics, 2022 Most mixed-flow pumps obtain a saddle-like Q-P curve with a backflow, owing to the increased incidence angle at low flow rates. The backflow was developed near the shroud and followed downstream again at its end to form a recirculating flow. The rotating

Generation and focusing of a second-order vector beam using a subwavelength optical element
Компьютерная оптика, 2022 This article proposes a new type of subwavelength axicons for creating and focusing second-order vector cylindrical beams. It is also shown that using the proposed subwavelength axicons, it is possible to create focal spots with an energy backflow.
