Hello,

I am trying to plot the dispersion diagram for a CRLH TL unit cell using cst eigenvalue solver. Does anyone knows how to proceed to get the dispersion for both RH and LH TL?.... how do i confirm whether the structure is a CRLH or not?


Thanks in advance
 




can you solve the problem???
 

I don't know CST, but the dispersion process should be the same for both RH and LH bands - you just want to solve for at least 2 modes. The structure is CRLH if it has modes with both positive and negative slope.
