| 摘 要： | 传统的电磁场理论教学在讲授时谐电磁场和均匀平面波等重要内容时采用的数学形式是相量法。本文从傅里叶变换出发重组了时谐电磁场和均匀平面波的内容安排，指出从傅里叶变换视角教授更能凸显时谐电磁场和均匀平面波的物理意义和重要性。通过相量法和傅里叶变换的对比，指出相量法是傅里叶变换的简化数学形式。教学实践验证了这一教学具有较好的教学效果。

| Abstract: | Phaser method is used in traditional electromagnetic field theory education for teaching time harmonic electromagnetic field or homogeneous plane wave. In this paper, the content of time harmonic electromagnetic field and homogeneous plane wave is reformed based on Fourier transform to make the physical meaning and importance stand out. Afterwards, the conclusion is drawn out that phaser method is some kind of simplified mathematical form from Fourier transform through comparing both of them. The practice had proved that the benefit of such a teaching mode. |
