I am trying to simulate a multi junction solar cell (for eg: Si/SiO2/Al) and trying to study the electromagnetic behavior of it. For periodic conditions I had used floquet boundary conditions,
I think giving the k-vectors for each layer in the structure in the floquet boundary conditions box is necessary, as the refractive index is different for different layers in the structure. Because of this the source and destination wave vectors are different. Am I right?
or
Giving the incident k-vector is correct?
Thanks in advance

Best.

I think if you have homogeneous mediums and the surfaces of your medums are perpendicular to periodic boundaries, there is no need to specify different types of Floquet, because only that component of the k-vector is importnant for Floquet periodicity, which is perpendicular to boundaries. This component is tangential to surfaces with different n and from Maxwell`s equations we know that this component is equal in each medium.
