HFSS&Cavity Filter

Hi everyone

I am studing cavity filter now.i hvae many question to know from you..

The first question is : how to simulate K in HFSS. I found something wrong with is ,the value which i simulated from hfss is different from practice tested.

some one have good idea?

if you want help me ...

Not sure if you meant coaxial combline filters or empty cavity type. They are almost always used interchangebly. Either case, the example presented using HFSS should help.
