摘要
光与介质分子相互作用是一个活跃的研究领域,新的现象、技术和理论不断出现,原有理论对解释某些新的现象遇到困难.本文应用法拉第电磁感应原理研究了分子中电子云与光波之间的相互作用,提出了在光波作用下介质中存在的一种分子电流机制,这种电流的密度随磁场的时间变化率增加而增大,它不同于介质分子的极化电流和磁化电流.这些工作有助于深入认识光波与介质之间的相互作用.
Research on interaction between medium and light has been an important and active field. New phenomena, applications and theories in this field have kept appearing over the past decades. Various explanations and theories for these new phenomena have been presented. The contradiction between the existing theory and the new experimental results indicates that the interaction between medium and light is a very complicated subject, and so far about which we do not know very well yet. In this paper, we investigate the reaction of medium on light according to Faraday＇s Law of induction. A mechanism of molecule current in medium in- teracted with light was presented. The density of this current increases as change rate of magnetic field increasing. This helps us to understand the interaction between medium and light.
