I WANT TO EXTRACT S11_PHASE; S11_MAGNITUDE;S21_PHASE and S11_MAGNITUDE
my unit cell is a SRR simylated with CST

i WANT my files to be like this files
View attachment S21_abs.txt
View attachment S21_phase.txt
View attachment S11_phase.txt
View attachment S11_abs.txt

i try to do it BUT i get the data like this
View attachment S21_ABS.txt
View attachment S21_PHASE.txt
View attachment S11_PHASE.txt
View attachment S11_ABS.txt

which means i have a problem with extracting data
please where is the problem ?
 

Please explain a bit your problem.
With CST you can export your data in form of text file which you are already doing.
number of data points to be stored and scale is default for CST
Do you want to store a particular number of data points?
 

thanks for your reply
no, the problem is that data are wrong
because i found this when i simulate the code with my extraction file
srr.PNG
i dont have any LEFT handed proprieties
the true result is
srrTrue.PNG

i think the problem is that i cant extract the true data from cst
can please tell me how i can find S11_PHASE and S11_MAGNITUDE
 

keep one very basic thing in mind CST exports the data of plot which is open in the window so you have to be little careful in this regard.
About the magnitude and phase when plot is open then in on the top you can see the options for magnitude and phase just by pressing that tab you can get the information about phase and magnitude and then you can export it
 

Hi,

I am working on matlab linking with cst, I am getting s11 (linear) in a txt file, using
result = invoke(mws, 'Result1D', 'a1(1)1(1)');
command. I want s11 in dB. how to do it.?

Thanks in advance.
 

Are u sure that your matlab code is correct?

Did u solve ambiguity issues?
