    how to simulate the coupling coeffent by hfss

    Hi, James, I want to know which mode should i use in order to get the coupling coefficient? Can I get the coupling coefficients using the eigenmode simulation? If so, does it mean I need to set the number of modes to be 2 in eigenmode? It costs me much time when I scan s21 curves...

    Can HFSS privide an equivalent RLC circuit for a resonator

    rlc circuit of cavity Can HFSS privide an equivalent RLC circuit for a resonator cavity? A resonator cavity with a shunt post in it, and simulated by HFSS. My question is: Can the shunt post be changed to the RLC equivalent circuit? If can, how? Thank you for your help!

    How solve the HFSS port problem-no conductors

    HFSS problem: When I am using the HFSS v11, one error occurs and I cannot assign port. The error information: No conductors were found on port, so auto assignment of conductors on that port cannot proceed. In the model, I use Vacuum and do some operations like "unite", "subtract", and...

    How can I find the resonant freq at each pass?

    Dear Cesar, I also use v11. At this moment, what I most want to do is change one varable/parameter and run and then analyze the result. I have no optimetrics. It is very boring and makes me tired. Can you guide me how do this automatically without optimects. i.e., Automatically change the...
