Note that HFSS calculates generalized S-param which means that the reflection coefficient equals to S11 and transmission coefficient is equal to the S12.radio09 said:Hi,
Could some one help me in understand how to plot the result of a single sell cell of an FSS structure simulated using floquet port as described in the above literature HFSSFloquet.pdf. I would like to know how to get the transmission and reflection coefficient. Also the S11.
My first post here and am trying to learn the tool.
Thanks a lot.
Thanks, i really need it~A guide to Floquet port in HFSS v11
In my opinion, floquet port is also a kind of feed or excitation.the mode TE and TM should cover all the situation, I think. I wonder if my opinion is right.Hi everyone,
If I have an antenna that must be feed at the bottom of the air box (where the Floquet port should be positioned) how can I make a simulation in this mode?
Thanks
The transmission coefficient from port 1 to port 2 is S21, not S12.Note that HFSS calculates generalized S-param which means that the reflection coefficient equals to S11 and transmission coefficient is equal to the S12.
I agree with friendchip, but it should be noticed that Floquet port is matched in all frequencies, however, the feed is not. I think first you should make sure that the Floquet port (with specific settings) and the feed launch the same field pattern (i.e. same TE/TM modes) so these two will have the same matching condition. You can easily figure out which mode is excited by the feed (using the geometry of the feed and it's probably one of the fundamental modes) and configure the Floquet port to excite the same mode.In my opinion, floquet port is also a kind of feed or excitation.the mode TE and TM should cover all the situation, I think. I wonder if my opinion is right.
