In this paper, experimental study was undertaken to investigate the effect of excitation frequency of a synthetic jet on the generation of a longitudinal vortex produced by the interaction between a jet and a crossflow in a wind tunnel.

Enhancement of Optical Spin-Orbit Coupling in Anisotropic ENZ Metamaterials
Vector vortex beams which possess complex intensity and polarisation patterns, and phase or polarisation singularities are important in a variety of applications ranging from high resolution imaging and data transmission to nonlinear optics and quantum ...

Generation of Arbitrary Longitudinal Polarization Vortices by Pupil Function Manipulation
The properties of optical vortex provide new insights into a wide range of optical and physical phenomena, giving rise to numerous applications in multiple disciplines. Notably, as much as the associated technologies have become increasingly flexible, it

Using the Richards–Wolf diffraction integral, the longitudinal energy evolution on the focal plane of the fractional order vector vortex (FOVV) beams was studied. These beams possessed a vortex topological charge n and a polarization topological charge m,

Ground-based ionospheric, CHAMP/STAR, and GOCE satellite neutral density ρ observations under deep solar minimum conditions were used to find whether there is a dependence of longitudinal variations on polar vortex strength. Ionospheric stations at fixed-

To reasonably divide the types of flow units along the latticework subchannel, one must prepare for the establishment of a one-dimensional fluid network model of the latticework in the middle region of the turbine blade.

In earlier works by the present authors, it was shown that a large cross-flow excitation is induced to a circular cylinder by setting another cylinder downstream in a cruciform arrangement with a certain gap between them, caused by longitudinal vortices ...

Longitudinal vortex structure in the flow field produced by a vortex ring impinging on a flat plate
The flow field produced by a vortex ring at Re = 2600 impinging on a flat plate was examined in detail using the smoke visualization method. The longitudinal vortex structure with a finger-like configuration was found which plays a crucial role in forming azimuthal coherent structures with a cross section that resembles that of an orange; the ...
