HFSS Problem

hey, guys. I'm a newbie in filter design. I have got a problem.
Is anyone know how to obtain the curve between resonator spacing and coupling coefficient K by using HFSS.
thanks.

hi,
first you should define the space between 2 resonator as a design parameter,then define an equation for K=voltage1/voltage2 for resonators.
now you can sweep spacing and caculate then plot the significant curve.
regards.
