摘要: 研究了电磁波在左右手介质界面折射与反射的特性,给出了折射系数和反射系数,从另外一个方面探讨了最小作用量原理在左手材料中的适用性;从电动力学和最小作用量原理证明了Snell定律,验证了Snell定律在左手材料中的适用性,并且得到Fresnell公式在左右手材料中的一致性.

关键词: 负折射率, 左手材料, 反射系数, 折射系数, 最小作用量原理

Abstract: The basic character at the interfaces of the positive and negative media is studied. The reflection coefficient and refraction coefficient are also given; the analysis shows the versatility of the principle of least action, Snell's law and Fresnell's law in the research on the left-handed material, and the negative refraction effect is explained.

Key words: negative refractive index, left-handed material, reflection coefficient, refraction coefficient, principle of least action
