چکیده
Based on the excellent and broad prospect of vortex beams in military application, it is necessary to evaluate scattering characteristics classical Bessel beam upon a perfect electrical conductor (PEC) blunt cone model aircraft structure. First, expanded by series plane wave spectra. Then, combining physical optics (PO) method, scattered field object fitted facet elements can be calculated. The amplitude, phase, orbital angular momentum (OAM) spectra for different attitudes are discussed detail. results show that backward still retains good OAM characteristics, which distorted with increase oblique angle. Besides, backscattering radar cross section (BRCS) also calculated analyzed, degenerated zero-order compared verify correctness proposed theory. Compared waves, provides new degree freedom, providing more information detection.

Tunable stimulated Raman scattering by pumping with Bessel beams.
We report on a novel pumping scheme for stimulated Raman scattering (SRS) that uses a Bessel beam. We have used this scheme for SRS from molecular vibrations in acetone and from a polariton mode in a LiIO(3) crystal. A nearly diffraction-limited Stokes beam was observed along the cone axis of the Bessel beam. The generation mechanism of the Stokes beam is identified as being due to noncollinear...
متن کاملEntangled Bessel-Gaussian beams.
Orbital angular momentum (OAM) entanglement is investigated in the Bessel-Gaussian (BG) basis. Having a readily adjustable radial scale, BG modes provide an alternative basis for OAM entanglement over Laguerre-Gaussian modes. We show that the OAM bandwidth in terms of BG modes can be increased by selection of particular radial wavevectors and leads to a flattening of the spectrum, which allows ...
متن کاملElastic Scattering of Electron Vortex Beams in Magnetic Matter.
Elastic scattering of electron vortex beams on magnetic materials leads to a weak magnetic contrast due to Zeeman interaction of orbital angular momentum of the beam with magnetic fields in the sample. The magnetic signal manifests itself as a redistribution of intensity in diffraction patterns due to a change of sign of the orbital angular momentum of the electron vortex beam. While in the ato...
متن کاملNonlinear Bessel beams
The effect of the Kerr nonlinearity on linear non-diffractive Bessel beams is investigated analytically and numerically using the nonlinear Schrödinger equation. The nonlinearity is shown to primarily affect the central parts of the Bessel beam, giving rise to radial compression or decompression depending on whether the nonlinearity is focusing or defocusing, respectively. The dynamical propert...
متن کاملPropagation of apertured Bessel beams.
The propagation features of several apertured Bessel beams are numerically calculated. The calculations show that the relations of axial intensity versus propagation distance are similar to the radial distribution of the aperture functions, which may be helpful in choosing the proper aperture functions in experiments.
