Re: mpb-discuss Digest, Vol 60, Issue 3 (2D Photonic Crystal (PC) vein structure)

Here's what I wrote:

(set! num-bands 8)

(set! k-points (list (vector3 0 0 0)(vector3 0.5 0 0)(vector3 0.5 0.5 0.5)(vector3 0 0 0)))

(set! k-points (interpolate 4 k-points))

(set! geometry (list (make block (center 0 0 0)(material (make dielectric (epsilon 8.9))) (size 6.2831 6.2831 6.2831) ) (make block (center 0 0 0)(material air)(size 5.2464 5.2464 5.2464) ) ))

(set! geometry-lattice (make lattice (size 1 1 no-size)))

(set! resolution 32)

(run-tm)

but i doesn't work properly :/

?? Hi,
?? you have to define a block with the approriate width in x and y direction?instead of cylinder with radius.hope this help

Hey There everyone,
?
I've recently downloaded the mpb package and installed it correctly, so everything seems to work fine. I saw that there are different examples of C++ codes to compute 2D PC band structures when the crystal is made of?a square lattice?of columns consisting of a material with a di?erent dielectric constant, with?
radius r=0.2a (a being the side lattice) and dielectric constant ?=8.9.?
Now I'd like to compute the PC band structure in the case where the crystal is made of
veins (width=0.165 a) distribution of dielectric material, but I don't manage to write the correct C++ code for this to happen.
Can please someone give me a hand?
?
pietro?
