====================================
Implementation Details
The element is defined by the following s-parameters matrix:
$$S(f)=\begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 2G & -2G & -1\end{bmatrix}$$
Where \(G\) is the ‘gain’ property. If the element is disabled, it is assumed the value of \(G\) is one (short circuit).
