The short-circuit admittance matrix of a two-port network is
\(\left[ {\begin{array}{*{20}{c}} 0&{ - \frac{1}{2}}\\ {\frac{1}{2}}&0 \end{array}} \right]\)
The two-port network is
1
non-reciprocal and symmetric
2
non-reciprocal and not symmetric
3
reciprocal and symmetric
4
reciprocal and not symmetric
