极慢表面等离子体:理论与实践

Very slow surface plasmons: theory and practice

V. S. Zuev, G. Ya. Zueva

摘要:

本文是一个方法论的特点,并作为一个目标,给出了一个简单的概念,理论和实际应用的非常缓慢的光学等离子体。它们存在于金属-电介质的边界上,即,在非常薄的金属膜和纤维上,并且作为驻波存在于金属球和椭球上。本文的特点是拓宽了各种空间的电磁模、自发发射概率、光学成象的产生、光学聚焦的极限和光子线动量等共同概念。所有提到的研究都是近年来完成的。介质中的光子动量问题,从闵可夫斯基和亚伯拉罕的著名论文发表开始,一直是争论不休的话题。调查了各种实际应用:将原子自发发射极大地增强为金属纳米颗粒的等离子体激元场模式的实验,将光辐射聚焦为基本上小于衍射极限点的点的实验,产生具有基本上小于衍射所限定的细节的图像的所谓的接近完美的Pendry透镜,以及最后,等离子体激元中的光子机械线性动量的百倍或更多放大的概念。所完成的工作得到了RFBR的支持,赠款编号为05-02-19647,07-02-01328。

英文摘要:

The paper is of a methodological character and has as a goal to give a brief description of the concept of theory and practical application of very slow optical plasmons. They exist on the metal-dielectric boundaries, namely, on very thin metal films and fibers and as standing waves on metal spheres and ellipsoids. The material presented in the paper features by widening the common concepts of electromagnetic modes of various spaces, of the probability of spontaneous emission, of creation of optical images, of the limits of optical focusing, and of the photon linear momentum. All mentioned studies are completed in recent years. The problem of the photon momentum in a dielectric medium was the topic of irreconcilable disputes for 100 years starting in the time of appearing of Minkowski and Abraham famous papers. Various practical applications are surveyed: the experiments with a great intensification of an atom spontaneous emission into a plasmonic field mode of a metal nanoparticle, the experiments on focusing optical radiation into a spot that substantially smaller than a diffraction limited spot, a so called near perfect Pendry lens that produces the image with details that substantially smaller than defined by diffraction, and lastly, the concept of hundredfold and more magnification of a photon mechanical linear momentum in a plasmon.
