Transmission line teaching aids using slow-wave transmission line technique

This paper propose a novel transmission line teaching aids using slow-wave transmission line technique. This teaching aids can help student observe the behavior of the electromagnetic wave in transmission line directly. This direct observation is important for the undergraduate who just study electromagnetics because the behaviors of the transmission line are abstractive, and hardly to be imagined. The proposed slow-wave transmission line is concatenated with multi large inductances and capacitances. By using LED lights, student can easily observe the behavior of the forwarding wave and the standing wave in the transmission line. The teaching aids can help the students understand the behavior of the electromagnetics wave in the transmission line effectively.
