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.

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 electron behavior from
this experiment, which had never been done FWIU: "How Electricity
Actually Works" (2022) https://www.youtube.com/watch?v=oI_X2cMHNe0 )
I recreated Veritasium's setup in my simulator and measured the current through the load resistor, the results of which are here:

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.
That's exactly right! In my simulation quantities like E and J are vectors with x and y components. In contrast B can be thought of as a vector (or bivector, technically) pointing in the z direction, but since it it only has one component it's simpler to just lump it in with the other scalars. (Aside: Having the simulation be in 2D brings in some interesting toplogical restrictions on circuits).
