摘要
利用方向阻抗概念,将电磁波斜入射的反射系数和透射系数与垂直入射的相应系数从形式上联系起来,采用直观形象的比拟使复杂的斜入射平行和垂直极化的反射系数和透射系数公式变得简单易记,有助于学生在学习这部分内容时更好理解.最后深入探讨电磁波全反射时容易产生疑问的能量守恒问题.
Abstract
The concept of directional impedance is used to link the reflection coefficient and transmission coefficient of a plane wave at oblique incidence angles with the corresponding coefficients at normal incidence.The intuitive analogizing makes the complex formulas of the reflection coefficient and transmission coefficient at oblique incidence easy to remember.The analogizing also helps students to better understand the content.Finally,the energy conservation problem at total reflection is discussed.
