Hi Gong,
I dont think the robust method proposed by X. Chen deals with number of resonance. It works for both single or multi resonance structures.
For data flip, in my opinion, it can be explained by the accuracy of 2nd-order iterative method. When the retrieval values of Re(n) are in range...
effective refractive index in cst microwave
sorry because of late replying, i'm on vacation.
i upload C-code which is based on Robust method, you can refer and let me know if you have any comment.
matlab code+refractive
ok i am going to upload some papers which i think to be important
first is robust method paper, second one is another paper that mentioned about the different calculation in homo and inhomogeneous structure. I think you can verify ur code by using data from second paper...
rcwa matlab
hi all,
for everybody to be interested in retrieving effective eps and muy, i found that if you obtain eps and muy from CST data (Sij amplitude and phases), the results could be wrong because of phases. It should be inversed in some cases but actually I dont understand clearly...
retrieval refractive index
as I told, I used Robust method to extract effective parameters. I think it better than the method Smith mentioned in his paper (PRB, 65, 195104). I guess you used Sij for different thickness (L) to choose the correct branch of Re(n) (linear fitting of nkL versus...
touches periodic boundary!
hi all,
I am reproducing the cut-wire pairs structure (in metamaterials). I used the periodic boundaries in X and Y directions, and open boundary in Z. But it always shows the above error. How can I fix it? And about setting up E field and H field, is it nescessary...
effective refractive index+weighed average
hi all,
it's great discussion.
i am also studying same prob. As abuantenna said, I also read "Robust method to retrieve the constitutive effective parameters of metamaterials" paper and "Determination of effective permittivity and permeability of...
