Dear;
When using optical moudle of siesta to calculate optical property of
monolayer graphene, we can get *dielectric permittivity (
episolon=epsilon_real + iepsilon_img) \ complex refractive index( **n**=n+ik
*) etc from results,but not *magnetic permeability(miu)*.
When consider the relation between epsilon\miu\n,I find
*n**=sqrt(epsilon)*,which
means *miu=4*pi*10^(-7)*,ie magnetic permeability of graphen is a constant,
just like air.
Is it right that magnetic permeability of graphene is a constant?
If not,how do we set the fdf profile to correctly calculate magnetic
permeability of graphene?
The attachment is the fdf profile I used.
Hope your explaining!
Best wishes!
