We present a robust interferometric method to generate arbitrary vector beam modes by
diffracting a Gaussian laser beam from a spatial light modulator consisting of a high …

Nondiffracting vector Bessel beams are of considerable interest due to their nondiffracting
nature and unique high-numerical-aperture focusing properties. Here we demonstrate their …

Methods for generating beams with arbitrary polarization based on the use of liquid crystal
displays have recently attracted interest from a wide range of sources. In this paper we …

Based on an analysis of polarized Bessel beams using the Hertz vector potentials and the
angular spectrum representation (ASR), a general description of transverse mode Bessel …

Non-separable superpositions of polarization and spatial modes in Gaussian beams have
shown rich patterns of spatially-variable polarization encoded in the transverse mode of the …

In this paper, we present a transverse electric (TE)-polarized Bessel-beam antenna in the
microwave range based on a leaky radial waveguide. According to the dispersion equation …

Negative propagation is an uncommon response produced by the local sign change in
Poynting vector components. We present a general Poynting vector expression for all …

Overshadowed by the electric dipole ones, the magnetic dipole transitions of a quantum
emitter are hard to probe. This can be remedied by using pure magnetic hotspots, which …

We consider the formation of a small focal spot, which has been reported in [J. Opt. Soc. Am.
A24, 1793 (2007) 10.1364/JOSAA. 24.001793 JOAOD61084-7529], by separating a higher …

We experimentally demonstrate the generation of radially polarized Bessel–Gaussian
beams from a c-cut Nd: YVO_4 laser with a hemispherical cavity configuration by proper …
