CST MWS questions
if you don't use a housing for your filter,you can set boundery to open.
is that the case? I set the boundary to open but eigenmode solver does not work. that why i am curious.
Eigenmode solver must have well defined boundary conditions. Open resonator isn't this case.
Yes, you can simulate the planar structural filter by eigenmodel solver(modal analysis) in CST. But you should set the boundaries to PEC for eigenmodel solver, that is to say the structure you will simulate should be closed by PEC. If the structure is closed, you can add space by 1/4 wavelength to the boundaries and then set the boundaries to PEC.
:) Hi :)
In help>content>setting up simulation>which solver to use,
it defines that the eignemode solver can not be used with open boundaries, lossy materials, lumped elements or discrete ports

it is important the dimension of the ports too

unfortunately, MWS's eigenmode solver can't work with the open conditions, but HFSS can do.
