Thanks. I need hexagonal cross section nanowire lay on X-Z plane (hexagonal area on X-Y plane) so that I can propagate wave through the nanowire. What I found is the hexagonal shape may be used but it is not going to be in X-Y plane. IF you still think it is possible to draw hexagonal in X-Y plane (as fiber cross section), or even if we can propagate wave in Y direction instead of Z or X let me know please.
I look forward to hear from you.
Regards,
Mahmoud
