Dear All,
I have designed a dielectric filled cavity resonator BPM and want to measure its position sensitivity.
From the S-parameter anaylsis, I could observe difference in signal levels for offset positions even in monopole mode. This I believe happens as I am having 4 floating cavities...
I meant beam as a cylinder (a wire) across the cavity with PEC boundary condition.Then it is analogous to a test bench characterization setup. I have not tried with a gaussian beam, maybe that solves the issue. Thanks for the suggestion. Let me try it out and update here!!
Dear All,
Thanks for all the previous responses to my doubts.
I would like to simulate a beam in an offset position within a cavity. First I calculate the resonance cavity of the system (with no beam: I mean a cylinder with material properties as a perfect conductor is used as a beam...
Dear All,
I have this struggle to assign port excitation on a multiport resonant cavity using Driven Modal in HFSS. I am confused about whether should I excite all the 4 ports as a wave port (changing the edit source in HFSS drop down to 0 for the other 3 ports) keeping one port as an...
Hello Guys,
Sorry for the late response as I was on vacation.
The issue that I posted could be solved as I did not define the terminating boundary conditions properly. The resonance frequency drift is not beyond a few kHz.
However, I am interested in solving the same in Driven Modal and am...
I also felt this could be the reason but a shift of 5 MHz is too much I guess. Because in reality when we measure the S21 of the resonator (through pickups), I still read close to the simulation value but without the pickups. I beleive there might be overlap of some material properties. I also...
Dear All,
I got a close to reality resonance frequency with eigen mode solver (simulating the enclosed vacuum volume within the resonator but with no pickup included). When I try to use the driven modal solution type with the pickup also included as antenna, my resonance frequency is different...
Thanks for your response. The issue was as I imported the step file for simulation, it took the metal volume for vacuum and vice-versa. Hence, HFSS was actually simulating the wrong volume. Thanks once again for your response.
Cheers

Hi all,
I am new to this forum and getting used to ANSYS HFSS. I have a cavity resonator whose resonance frequency I want to determine. By solving using Eigenmode solution type, the eigenmode data would give me the resonance frequency and the Q. However, I believe the resonance frequency is...
