Problem # $2$

For the shown network, determine $S_{11},S_{34}$ and $S_{21}$

Input $(4)(2)$ Input

$S_{\text{C}\text{I}\text{C}}=\left[\begin{array}{cccc}0& -j\sqrt[\phantom{2}]{1-C^2}& C& 0\\ -j\sqrt[\phantom{2}]{1-C^2}& 0& 0& C\\ C& 0& 0& -j\sqrt[\phantom{2}]{1-C^2}\\ 0& C& -j\sqrt[\phantom{2}]{1-C^2}& 0\end{array}\right]$

where $C=\frac{1}{\sqrt[\phantom{2}]{2}}$
