Hello Rui,
the only thing happens here is scaling the 4 Maxwell equations under the
condition that c0 = 1.
The solutions are not unique, you can choose the scaling method, which
is more suitable for your problem. (for example, you can let the
permittivity as the value in the real world, or keep the length in meter
or mm, or if you want to calculate a real current value, you can also
keep the current in SI unit).
regards

Hi meep users,
I am new to meep and have some questions about units and sizes in the
code of meep.
I want to measure the transmission of a silicon plane with the wave of
1000nm. The relationship between frequency and wavelength is
wavelength=1/f. So I guess if I assume the 1 in my code equal to 150
nm, the relative wavelength of the source should be 1000/150 = 6.67, so
the f should be 1/6.67 = 0.15. Is my calculation correct? What if I set
the 1 in my code as 300 nm, that means I need to change my frequency
to 1/3.33=0.3. So will the two simulations have same result since I used
the different frequency but simulate the same model?
Thanks,
Rui
