hfss solution type eigenmode
thank you, I know how to do it now. but I have another question about the eigenmode:
In the setup window, you can fill "Number of modes". I tried 1,2,3,4,5, one for each time, and found out the calculated frequencies are all different....
I think the resonator should have infinite resonation mode, but at least the first few should be the same by calculating different mode number?
I know the equation for coupling coefficient is 2(f1-f2)/(F1+f2), so I should only set the mode number as 2?
Confused now and please help me.....
Added after 20 minutes:
somehow, I figured it out,
if simulation one resonator, use 1 mode
..................two resonator, use 2 modes
......
Am I correct?
thanks.
