论文摘要
在可见光的衍射中,始终会出现evanescent波的介电小圆柱包装。然而,单波发病率对应于圆柱体外的evanevanscent波的影响。在本文中,我们从理论上表明,撞击玻璃微雪板的一对对称的平面波对应于逃生波的更高影响。也就是说,逃生波对传播的波的干扰导致抑制具有非常小的横截面的区域中电磁场的抑制。该区域位于自由空间,距离微孔的后侧及其轴线}相当长的距离。它可以为冷原子和离子提供线性光学陷阱。
In the diffraction of visible light by a dielectric microcylinder packages of evanescent waves always arise. However, a single-wave incidence corresponds to rather small impact of evanescent waves outside the cylinder. In this paper, we theoretically show that a symmetric pair of plane waves impinging a glass microcylinder corresponds to much higher impact of the evanescent waves. Namely, the interference of the evanescent waves with the propagating ones results in the suppression of the electromagnetic field in an area with very small cross section. This area is located in free space at a substantial distance from the {rear side of the microcylinder and along its axis}. It may serve a linear optical trap for cold atoms and ions.
