Plasmonic oligomers in cylindrical vector light beams [PDF]
Beilstein Journal of Nanotechnology, 2013 We investigate the excitation as well as propagation of magnetic modes in plasmonic nanostructures. Such structures are particularly suited for excitation with cylindrical vector beams. We study magneto-inductive coupling between adjacent nanostructures.

A miniaturized acoustic vector sensor with PIN-PMN-PT single crystal cantilever beam accelerometers
Acta Acustica, 2020 Directional sound detection using vector sensors rather than large hydrophone arrays is highly advantageous for target detection in SONAR. However, developing highly sensitive and compact vector sensors for use in a system whose size is limited has been ...

Switchable phase and polarization singular beams generation using dielectric metasurfaces
Scientific Reports, 2017 Singular beams which possess helical phase wavefront or spatially inhomogeneous polarization provide new freedom for optical field manipulation. However, conventional schemes to produce the singular beams have difficulty in realizing the flexible switch ...

Generation of cylindrical and elliptical symmetrical vector beam on the Mach–Zehnder interferometer
AIP Advances, 2018 We propose a principal scheme to generate the cylindrical and the elliptical symmetrical vector beam based on a modified Mach-Zehnder interferometer. The modified Mach-Zehnder interferometer, the wave plates, the Polarizing Beam Splitter (PBS) and the ...

Efficient optical trapping with cylindrical vector beams
Optics Express, 2019 Radially and azimuthally polarized beams can create needle-like electric and magnetic fields under tight focusing conditions, respectively, and thus have been highly recommended for optical manipulation. There have been reports on the superiority of these beams over the conventional Gaussian beam for providing a larger optical force in single beam ...

A Low Complexity 2D Pattern Synthesis Algorithm for Cylindrical Array
International Journal of Antennas and Propagation, 2013 This paper proposes a 2D pattern synthesis algorithm for cylindrical array. According to the geometric characteristic of cylinder, we can regard a cylindrical array as an equivalent linear array whose elements are identical circular subarrays. Therefore,
