Hello 576650550, 

Thank you for reaching out to Ansys Learning Forum! 😄

It seems that for 30GHz, this material gives a non-positive conductivity. In case you have defined that in a frequency dependent way, please, make sure that for the whole frequency domain, its conductivity remains positive. 

Warm regards, 
Jason.
