scuff-transmission for 1d gratings

[gevero]

Hi Homer

I was wondering if is it possible to use scuff-em to model 1d periodic gratings. Of course something of this kind is possible using a properly formatted unit cell and the full calculation, nevertheless a purely 1d solution would be much faster, I guess. I saw that something along these lines is possible given that purely 2d casimir calculations are possible! Thanks a lot

Yes, it is definitely possible to model 1D periodic gratings. If you can describe the geometry in which you are interested and the results you would like to extract for this geometry, I can help you set up the calculation.

Hi Homer

Thanks for the quick answer. Below you can find two sample structures that I would like to simulate. Regarding the physical setup and the results I would like to obtain they are as follows:

• Incident Field: Plane wave with arbitrary polar and azimuthal angles. I guess that the arbitrary azimuth might be a tricky part, because in this case the problem is only pseudo 1d. The plane wave may come both from the top or the bottom of the structure.
• Calculated quantities: I need for sure Reflectance and Transmittance, or event better the reflection and the transmission matrix, which implies that I should be able to extract the polarization state of the reflected and transmitted fields. This is also tricky because it would be interesting to consider 2 separate cases, i.e. the first where all the diffraction orders are included, and the second where only the first diffraction order is retained.

Thanks a lot for your time and help
