摘要

根据Whittaker标量势理论,建立了圆偏振光束的矢量传输模型.基于这一模型研究了圆偏振光束在左手材料中的反常旋转特性.通过分析光束偏振态、衍射对强度质心旋转特性的影响,发现圆偏振光束在左手材料中旋转方向反转并揭示其旋转角等于古伊相.采用分析横向能流的方法,揭示左手材料中反向的横向能流是导致反常旋转特性的主要原因.对圆偏振光束在左手材料中反常旋转特性的研究,有利于增强对左手材料中光束传输特性的认识.

Abstract

According to Whittaker scalar theory, a vector transmission model of circularly polarized beam is established. Based on this model, the anomalous rotating characteristics of circularly polarized beam in left-handed materials are investigated. By analyzing the polarization state and diffraction, the abnormal rotation characteristics of beam centroid are revealed. When the circularly polarized light beam propagates in a left-handed material,the rotation characteristic is reversed and the corresponding rotation angle is equal to the Gouy phase. We find that this abnormal rotating characteristic is caused by the reversed transverse energy flow. These findings provide a better understanding of the transmission characteristics of beam in left-handed materials.
