    Waveport excitation and mode alignment

    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...

    Waveport Exciation in HFSS

    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...

    Driven Modal Port Excitation for Resonant Cavity

    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...

    Resonance Frequency in Driven Modal

    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...

    Resonant Frequency of a Cavity Resonator

    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...
