Dear Steven and MPB's user, I have a problem about MPB would like to discuss with you: I would like to calculate the band structure of the PC slab: (have a three layer). The first layer is the clad 1 (with refractive index n1, and thickness 0.2a); The second layer is the core (with refractive index n0, and thickness 0.1a); The third layer is the clad 2 (with refractive index n2, and thickness 0.3a). I define my structure as below: (n1 < n2 < n0)
(set! geometry (list (make block (material (make dielectric (epsilon eps1))) (center 0 0 -0.2) (size 1 1 0.2)) (make block (material (make dielectric (epsilon eps0))) (center 0 0 -0.05) (size 1 1 0.1)) (make block (material (make dielectric (epsilon eps2))) (center 0 0 0.15) (size 1 1 0.3)) (make cylinder (material air) (center 0 0 0) (radius r) (height 0.6)) )) It seems MPB does not support the asymmetric structure, because I check my structure by using this command: h5topng -x (-y) ....The cross structure that I get, is not correct! Please let me know why it is? Thanks, Nils Jensen ____________________________________________________________________________________ No need to miss a message. Get email on-the-go with Yahoo!
