Hi
I though that I knew interpolating sweep but surely I am wrong.
Problem statement as is follows I have to couple a spherical cavity with the coupler I have use Eigen solver to characterize the cavity which is high Q cavity and goal is to couple it with beta=9 means overcoupled.
I have sound grip on coupling theory. I did following steps.
1. Made an aperture on cavity to connect it with the coupler.
2. Aperture will shift the resonant frequency of cavity and it will not be 2.99801 GHz which is my solution frequency.
3. I used driven model with one wave port to excite the structure so it means I am available with s11 only
4. I used interpolating sweep from 2.96 GHz to 3.0 GHz with 10KHz step to scan for the shift of solution frequency.
5. I got some frequency with proper s11 all seems good
But
Issue is that when I tried to run same model with same setup but with single frequency which I found by interpolating sweep I get nothing.
Why when I get some point with interpolating sweep is not produced by single run at same frequency.
what is wrong?
Please I am tired with this problem
thanks in advance for your help
