Dear mpb-users,

I defined a 2D triangular lattice PCW with first rows ring-shaped and second rows vertically shifted. In the band diagram, I observed that the parts of the bands couple to each other at their intersection point, therefore there are some excess guided bands and the field distribution of the guided odd mode does not seem guided. How can I understand the accuracy of the upper guided band and the onset of extended modes?
Any help is appreciated.

Thank you very much.
Regards,

FulyaBagci
