Hi, i did follow this guide to realize a dispersion diagram https://www.emtalk.com/tut_3.htm, but when i try to simulate on HFSS , the simulator display an error about the radiation boundary is not support by egienmode solver , i try to change the pml charactestics from radiation only to somethingelse but I can't in eigenmode. Someone can help me ?
It would seem that there is a separate radiation boundary in your simulation. Check that a radiation boundary was not created alongside the PML - this can sometimes happen if you create a PML in a simulation of solution type other than eigenmode.

thx PlanarMetamaterials for your very fast answer , it seems to work now :thumbsup::thumbsup:, I have found the radiation boundary alongside the pml , thx you very much !!!! If I have some other questions I will write again :razz:
