Hi Simon Bridge, thanks for your reply...
I have tried using the following matrix:
[\
\begin{bmatrix}
1 & 0 \\
(n2-n1)/R2 & 1
\end{bmatrix}
x
\begin{bmatrix}
1 & d/n2 \\
0 & 1
\end{bmatrix}
x
\begin{bmatrix}
1 & 0 \\
(n2-n1)/R2 & 1...

Truthfully, I am not certain. I have read over the textbook again and the only possible explanation for adding a one is to have a net gain per round trip increase through the amplifier?
I have tried your suggestion and I obtained a value of 4.43x10^-4 cm^-1... at least it's not negative. Do...

I think that the <0 degrees just means that the sources are in phase but I think you are right in that they may be irrelevant in the calculations.
so, is this correct for Kirchoff's equation?
