- TL;DR Summary
- Can someone explain lumped element circuit model of transmission lines please?
This is for my graduate EM Theory class. My background is physics/optics, so I was able to understand when we solved maxwells eqs. for waves propagating between parallel conducting plates, but that lead into the lumped element circuit model of transmission lines which I don't understand. I've attached the figure we used. My question is why does the circuit look this way? Do the two horizontal wires represent the two parallel plates, or is the top one the transmission line and the bottom one ground? And how do we know that the RLC components should be arranged in this way instead of some other way?
