Earlier quoted context omitted.

On my info page ( https://brandonli.net/semisim/info ) there's a list of things my simulation can and can't do. After taking a look at the paper you mentioned, I think simulating it may very well be possible, however it might take a bit of effort. As for graphene, its band structure is different enough that I don't think it would work. Note that my simulation is intended for educational purposes only, not scientific…

Thanks, quite the useful simulator; I hadn't found that page yet. Additional considerations for circuit simulators: What does the simulator say about signal delay and/or propagation in electronic circuits and their fields? How long does it take for a lightbulb to turn on after a switch is thrown, given the length of the circuit and the real distance between points in it? (I learned this gap in our understanding of el…

I recreated Veritasium's setup in my simulator and measured the current through the load resistor, the results of which are here: https://imgur.com/a/sxVihf0

The gap between the wires is about 1 micrometer, so light should take about 3 fs to propagate through. The simulation output approximately matches this prediction, and over the first few tens of femtoseconds the current increases, with a jump at around 70 fs due to the reflected wave. All of this is pretty much in line with the results of Veritasium's experiment.

Thanks for bringing it up. I might include this as another example in my sim.

Nice.

These are cool _ wave propagation vids too; Nils Berglund wave visualizations: https://youtu.be/v0cZjOIfwos?si=07w2Wd4dPlGmNxHp

_: photon, fluid, standing transverse,, plasma

What about longitudinal waves in plasma, superconductors, and superfluids though? https://www.google.com/search?q=What+about+longitudinal+wave...

I suppose vorticity doesn't matter that much for classical electronic circuits
