plane wave expansion method matlab code

Hi,everyone,I'm doing some research on 2D photonic crystal slab based on SOI substrate. I know that the bandgap of it can be calculated by PWE and supercell method. But I don't know how to solve it by Matlab? How to define supercell? How to calculate the light line?
If anyone can paste some Matlab codes on this problem? Thanks a lot!

Hello:

For this you can visit h**p://groups.yahoo.com/group/pbg_analysis/ for furthur guidance. I am also attaching matlab codes I got from their forums.
Hope this helps.

I have also uploaded the thesis this code is based upon. All credits for the code and the thesis go to it's owner Dr. S Guo of Old Dominion University.

Dear zeroedus,
Thanks for your help very much! But I have not enough points to download the theses. Would you please email them to me? And the PWE directory has many matlab files, can you tell me what problems each one to solve?
My EMAIL: gdingshan@163.com

Very good! I am very eager to get these datum.

Thank you very much for this post. It was a huge help to me.

Thank you for your help.It is a good post.

Sounds very good information. Thanks!

hi gdingshan, now i meet the same problem as you mentioned above ,have you solved it , if you have ,could you tell me how to do it thanks

It's a good post, but i have not enough points to dowload the thesis.

Is there a FDTD writen by Dr. S Guo? Who can give me the FDTD program? My Email is zhh309@sina.com. Thanks a lot!

thank you very much for your materials ,I want it for long time .

in my opinion ,in his programs ,he change the TM and TE performance .right?

why not use MPB or Bandsolve to calculate it?

nice work. excellent implementation solving all my problems :D
i am brand new user. can someone email to me sarniak(at)tlen.pl the manual :/ instead of lack of points :D:D:D

that's great! I'm looking for the codes. Thanks a lot

could it be possible if the policy to be changed..I don't have enough points to download the thesis.
Or maybe someone who already have it,send me the file through my mail: khalmusa2@yahoo.com
Thanks

This is the matlab code that I'm looking for! Thanks so much.

Hi
i want to calculate the band diagram of a kind of structure that the supercell is in diffrent kind, can you help in this too?

i attach the structure here.

Thanks alot for your help

Has anyone applied Dr. Shangping Guo's Fast Fourier Transform Plane Wave expansion method described in his published paper "Simple plane wave implementation for photonic crystal calculations, Optics Express vol.11 p167 (2003)for "arbitrary lattice"? I tried to verify my code by appling his method to geometries with published band structures. The method works for symmetric lattice(square, triangular) with symmetric "atom"(circular, square) but didn't work for non-symmetric lattice (rectangular) or non-symmetric "atoms"(elliptical). I wonder if there is limitation of this method. Please help~~~
Thanks!

ychuang1 and I have the same question

Does anyone have any codes on the plane wave admittance method, or the Fourier transform design of photonic crystals?

zeroedus,
Thank you very much.
