HFSS use of Datatsets

Hello,

In HFSS I need to define a goal function (defined at a certain frequency) that is the absolute value of the difference between s11 and a reference function (which is frequency depended like dB(S(FloquetPort1:1,FloquetPort1:1)).
I need to perform the optimization at EACH FREQUENCY IN THE SWEEP, so that that in the "calculation range" box I specify only one frequency.
Since the constitutive parameters (eps,miu) are also frequency dependent, the idea is to repeat the optimization property line several times (one line per frequency)

I tried this expression in the Goal box (no quotes)

"abs(dB(S(FloquetPort1:1,FloquetPort1:1))-s11_db_ref_freq)" , where

s11_db_ref_freq is a function of frequency

I defined a dataset s11_db_ref_freq, and tried to write

Goal=abs(dB(S(FloquetPort1:1,FloquetPort1:1))-s11_db_ref_freq),

but HFSS does not accept this.

Note. I do not need any interpolation since the datasets are defined at frequencies where I need the optimization to be done.

Please see attached.

I guess I am not using the dataset correctly.

Please advise.

Thanks

are them have the same array size ?

yes
