like photonic crystal

in modeling of a nano wire array that periodicity embedded in matrix, with scattering matrix method what should i do? i don't understand how to layered them
please help me
is there any similar code for that?
this wires is ferromagnet and i want to calculate magneto optical activity of them

u can use any FEM simulation software, HFSS or COMSOL, with proper material properties...
or if you want your own code, there are a bunch of inverse scattering methods out there for layered structures.

Thanq so much, is there any similar code for that in internet? If it is possible please give me their links. Thanx again

it is not hard to write a similar code. check this out:
