Eigenmode simulation problem when frequency dependent material is added
I have a simple vacuum cavity with a small absorber at one of its sides. The problem is that when I define the material of the absorber as a frequency dependent material, the eigenmode simulation does not converge and stops with execution error.
Note that I used for "tab" files to define the permittivity, tan d, permeability & magnetic loss tangent of the corresponding material.
Thanks a lot for your help!!
