Abstract

This work considers an optical system that operates by both quadrupole transition and evanescent surface plasmons waves. The surface plasmons waves is generated by the total internal reflection, and its intensity is distributed in the vicinity of the surface. The theory of such an optical system is constructed, assuming the quadrupole transition is only allowed, and then the quadrupole optical forces and the ensuing reflection of Cesium atoms is shown. The emphasis here is on the role of the metallic capping layer with a finite thickness and a finite plasma frequency on the evaluation of atomic reflection processes. A desirable enhancement of the evanescent plasmons waves magnitude is obtained. At the same time, a significant decrease in the atom-surface attraction, which is considered one of the biggest obstacles in the atomic reflection process, is achieved. The performance of the atomic reflection process and some associated factors are pointed out and discussed.

表面等离激元波增强四极相互作用的来源

摘要

这项工作考虑了一个由四极跃迁和e逝表面等离激元波共同作用的光学系统。表面等离激元波是通过全内反射生成的，其强度分布在表面附近。在仅允许四极跃迁的前提下，构建了这种光学系统的理论，然后显示了四极光学力和随之而来的铯原子的反射。这里的重点是具有有限厚度和有限等离子体频率的金属覆盖层在原子反射过程评估中的作用。获得了e逝等离子体激元波幅度的期望的增强。同时，原子表面吸引力的显着降低，这被认为是原子反射过程中的最大障碍之一，已完成。指出并讨论了原子反射过程的性能以及一些相关因素。
