In media with strong spatial dispersion the electric displacement vector and the electric field are typically linked by a partial differential equation in the bulk region. The objective of this work i...
Tight focusing of a double-ring-shaped, azimuth ally polarize d beam
Tight focusing a double-ring-shaped azimuth ally polarize d beam
2013/7/3
We study the focusing properties of a double-ring-shaped azimuthally polarized beam through an annular high NA objective lens. It is shown that a subwavelength focal hole (～ 0:5λ) with a quite long de...
Fraunhofer diffraction of a Laguerre-Gaussian laser beam by fork-shaped grating
Fraunhofer diffraction Laguerre-Gaussian laser beam fork-shaped grating
2010/11/17
In this article we present a theoretical study for Fraunhofer diffraction of a Laguerre-Gaussian laser beam with zeroth radial mode number and azimuthal mode number l by diffractive grating with embe...
Casimir forces between conductors at the sub-micron scale cannot be ignored in the design and operation of micro-electromechanical (MEM) devices. However, these forces depend non-trivially on geometry...
