I am not able to calculate the scattering matrix of a pi-circuit although I have calculated its Y matrix. The needed scattering matrix is referred to 50Ω.
Could someone help me on calculating the scattering matrix?
I tried to deduct the S50 matrix using the attached picture https://ibb.co/G7JZBGY
however, I got at the end 2 non linear equations for 2 unknown variables
