After I repeat the simulation in ADS again, I got correct results.

Have you truely come to be able to understand calculation of "Γ_{in_corrected}" in Case-2 without using "stos()" ?

[Case-1]
S_Z₀₁_Z_L=stos(S_Z₀₁_Z₀₂, {Z₀₁,Z₀₂}, {Z₀₁,Z_L})
S_Z₀₁_Z_L(1,1) == Γ_in=(Z_in-conj(Z₀₁))/(Z_in+Z₀₁)

[Case-2]
S_Z_s_Z_L=stos(S_Z₀₁_Z₀₂, {Z₀₁,Z₀₂}, {Z_s,Z_L})
S_Z_s_Z_L(1,1) != Γ_in=(Z_in-conj(Z₀₁))/(Z_in+Z₀₁)
S_Z_s_Z_L(1,1) == Γ_{in_corrected}=(Z_in-conj(Z_s))/(Z_in+Z_s)

Hi pancho_hideboo,

I tried to evaluate input and output reflection coefficients in several ways, including Case 2 you mentioned. The results I obtained are all the same, as shown in the attached figures. If you have more comments, please post again. Thank you very much for your clear explanations, you are a great sensei.
