WebDec 24, 2024 · Utilization of cylindrical vector beams (CVBs) for excitation of plasmonic and all-dielectric nanostructures and their arrangements has recently become a subject of growing research interest... CVB, which possesses spatially inhomogeneous polarization distribution, is the axially symmetric solution to the full vector electromagnetic wave equation43,44,45. Due to the polarization singularity of CVB, it inherently has a null field in the beam center. The Jones matrix of the CVB with m-th polarization order … See more The working principle of metasurface-based CVB multiplexer/demultiplexer is schematically illustrated in Fig. 2. To uniformly distribute … See more We employ two metasurfaces as CVB multiplexer and demultiplexer, and the multiplexing/demultiplexing experiment is schematically depicted in Fig. 4. Four Gaussian beams carrying digital signals are incident on the … See more The characteristics of the produced CVBs have been experimentally investigated, where the experimental set-up is schematically shown in Supplementary Note 4.

WebCylindrical vector beams (CVBs) represent the most commonly used type and feature cylindrically-symmetric polarization distributions. The optical systems employed thus far … WebIn this paper, we simulate the focusing of a cylindrical vector beam (CVB) of second order, using the Richards–Wolf formula. Many papers have been published on focusing CVB, but they did not report on forming of the toroidal vortices of energy (TVE) near the focus. TVE are fluxes of light energy in longitudinal planes along closed paths around some critical … pain in knees and lower back
Cylindrical vector beams: from mathematical concepts to applications
WebCylindrical-vector beams are of increasing recent interest for their role in novel laser resonators and their applications to electron acceleration and scanning microscopy. In … WebNov 5, 2024 · It was shown that tightly focused cylindrical vector beam of m-th order produces reverse energy flow in the focal plane ( m =2). If m =3 the reverse energy flow … WebJul 1, 2024 · Cylindrical vector beams (CVBs) are the most common example of such light beams. The polarization state of CVB can be theoretically described by the high-order Poincare sphere (HOPS), whose two poles are two orthogonal circularly polarized vortex beams with opposite topological charges. pain in knees when jumping
