Dear Meep users,
I have got the Polarizabilities in Meep units for a=1µm and would now like to use these in a simulation with a=1nm. Since the unit of the polarizability is A^2 s^4 / kg I want to convert the meep units back to SI and then to the new Meep units. The unit of time is set by the unit of distance, so a=1µm defines my unit of time as 10^-6m/(3*10^8 m/s) for one Meep unit. How do I handle the A and kg? What are the units for current and mass in Meep?
Thanks a lot for your help!
Regards,
Stefan
