I've made a program to help visualize some transmission line phenomena.

Thanks, Roy. It is very interesting.

I'm having a hard time getting my head around Demo 5. The waves go away
periodically (every 8 wavelengths?), sort of like a squegging oscillator.
(By the way, it appears that the line is two wavelengths long rather than
three.) This was totally unexpected. I will think more about this and try to
picture the reason.

Nice tool.
