Hi everyone, I am currently working on the simulation on Fbar filter using this software, I am having problem with plotting the S-paramter ( S11 and S21). Anyone know how to use the admittance result to plot the S11 and S21?

Have you tried this formula---- (1-es.Y1150[ohm])/ (1+es.Y1150[ohm]) ？

Have you tried this formula---- (1-es.Y11*50[ohm])/ (1+es.Y11*50[ohm]) ？
