为促进电磁波理论的教学工作,本文提出了一种极化电磁波的教学实验方法。用这一方法可以简便地将线极化电磁波转变为椭圆极化波或圆极化波。本文给出了这一方法的实验原理、计算机辅助分析程序、计算曲线、实验步骤和实验结果。实践证明,通过这一实验可以使学生较牢固地掌握电磁波的入射、反射、极化和相移等较为抽象的理论和概念,增强分析问题和解决问题的能力.
In order to promote the teaching of electromagnetic wave theory, this paper presents a teaching experiment method of polarization electromagnetic wave. With this method, the linearly polarized electromagnetic wave can be easily converted into an elliptically polarized wave or a circularly polarized wave. This article gives the experimental principle of this method, computer aided analysis of the program, the calculation of curves, experimental procedures and experimental results. Practice has proved that through this experiment, students can grasp more abstract theories and concepts of electromagnetic wave such as incidence, reflection, polarization and phase shift, and enhance their ability to analyze and solve problems.
