Let me give you some background of problem.
I am designing a coupler which has to be over coupled as a part of my project.
I used Eigen solver with PML as boundary condition and based on loaded Q value and field in cavity successfully found the exact coupling slot at the resonant frequency. From this value of coupling I can very easily calculate s11 and I know the frequency.
Problem is when I try to simulate the same model using HFSS driven model with PML replaced with port I do not get anything at that frequency even frequency sweep does not return anything while the filed inside the structure is exactly the same as calculated with Eigen Solver.
I am sure I am doing something wrong but I need to know.
Thanks in advance for help
