The basic physics of traveling waves and standing waves are fundamental topics in the education of science and engineering students. These concepts are found in many areas, including classical mechanics, quantum mechanics, and electromagnetism. Typically, laboratory demonstrations of traveling waves and standing waves are based on mechanical systems such as vibrating strings and sound waves. This paper presents a simple benchtop experiment for producing and observing electromagnetic standing waves in a coaxial cable and determining the phase velocity of their underlying component traveling waves. We also discuss the experimental requirements for this experiment.

同轴电缆中的驻波：用于教学波实验室的简单且低成本的实验

行波和驻波的基本物理学是理工科学生教育的基本主题。这些概念存在于许多领域，包括经典力学，量子力学和电磁学。通常，行波和驻波的实验室演示都是基于机械系统（例如，振动弦和声波）进行的。本文提出了一个简单的台式实验，用于产生和观察同轴电缆中的电磁驻波，并确定其基础分量行波的相速度。我们还将讨论该实验的实验要求。
