Hi, 2D calculations means that your block have no size in Z direction. secondly, the size of your block is too larger than your lattice, you said that sx=1, and your block's size is 6.2831, so you may increase sx, for example 10, or you may reduce the block size too 0.62 for example if you want conserve sx equal to 1. Best regards

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

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? ------------------------------------------------------------------------------- Valore legale alle tue mail InterfreePEC - la tua Posta Elettronica Certificata http://pec.interfree.it ------------------------------------------------------------------------------- -----Inline Attachment Follows----- _______________________________________________ mpb-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/mpb-discuss -------------- next part -------------- An HTML attachment was scrubbed...
