Wondering why the two passive devices have the same mac address...

Nice catch, I haven't read the paper yet but I wonder if it belongs to the device generating the frequency.
Shouldn't since the passive devices build the packets the MAC is probably the same because it's they just copied the same exact fpga code on both devices.

What wasn't clear and should be mentioned is that the active device doesn't have to transmit wifi at all it's just a source of random rf radiation at compatible frequencies since you craft packets by selective reflecting the signal.
