Hi,
https://www.dropbox.com/sh/lof3o1wfjpdbu2b/WwjiYBku2Z
Here is the link. I am trying to get figure 4 of the paper.
I have used scattering boundary conditions. I can get the
magnetic field distribution of the wave guide but not the
transmission spectra. Thank you so much for your help
Post by Katte NkorniWhich version of Comsol are you using? I should be
able to help you.
Post by Katte NkorniGo to the final layer and plot the S11 parameter.
Previously you should have made lambda a parameter
Then in the frequency input. type c_const/lambda
You also have to define the refractive index as
function of wavelength in the global definition function
region.
Post by Katte NkorniSave your program in a dropbox and email the link to
me. I should be able to fix it for you.
