Hi all, I'm simulating a simple coupled line microstrip resonator.
Basically, I just want to characterize a series of channels from 200GHz to 300GHz by changing the length L of the resonator. The step size preferred is about 1 micron (L changes in a geometric sequence) from 150 micron to 250 micron.
However, it looks some of the resonance peaks returned by HFSS are OVERLAPPED or DISORDERED (f_res should change 'monotonically' with L), although the general trend looks very good. I really want to get a series of more or less evenly-spaced channels over that frequency range.
Can anyone tell me if my step size have reached the resolution limit of HFSS? Should I change the "model resolution" settings? How can I get rid of those overlaps and disorders?
