Is posible to add a mirror/boundary condition on one side? #54
Comments
It is not directly possible. Actually it would be a nice project if someone had the time for legume projects... :) There's probably an analytic expression for the modes of the system with a mirror, and once you have the correct basis, everything else should just work! There is actually a work-around too. The mirror can be replaced by just literally mirroring the system, and the difference between PEC/PMC is just the difference in which of the sigma_xy reflection modes you incorporate. I know that this works very well for a slab that's sitting directly on a mirror. That is to say if you have something like air -> slab of thickness d -> mirror, you can simulate this by just doing air -> slab of thickness 2d -> air. In your case, you can try something like air -> slab -> air x 2 -> slab -> air. However, one potential problem I anticipate is finding the basis modes of the two very weakly coupled, identical slabs. The modes will be very close to degenerate and I'm not sure if |
Ok, thanks I will try using that approach. I have problems where the air/dielectric between both are not very thick so it may work. Thanks again. |
Hello,
I have checked the examples, but I am wondering if it is possible to calculate the bands for a structure with a bottom mirror. For example a slab with a pattern with air above and below, but as boundary condition or adding an additional layer with a the bottom a mirror. Something like this,
Open/Air/Slab/Air/Mirror
Thank you,
