Hi mariamel,
post your hfss design here and i will take a look and try to help .
did u define the ferrite material by yourself?when u define the material u should pay attention to the units u use(Gauss,Oe,A/m).
guy .

Hi Guy,
i'm very grateful that you want helping me, so here it is my hfss design : it is a ring with a microstrip line on ferrite substrate; i wait your answer impatiently.
