reciprocity

Consider a two-port network with the transmission matrix: T = $$\begin{bmatrix}A&B\\C&D\end{bmatrix}$$. If the network is reciprocal, then

If the scattering matrix [S] of a two port network is $$$\left[ S \right] = \left[ {\matrix{ {0.2\,\angle \,\,{0^ \circ }} & {0.9\,\,\angle \,\,{{90}^ \circ }} \cr {0.9\,\angle \,\...

The short-circuit admittance matrix of a two-port network is $$$\begin{bmatrix}0&-\frac12\\\frac12&0\end{bmatrix}$$$ The two port network is

An antenna when radiating, has a highly directional radiation pattern. When the antenna is receiving its radiation pattern

For a 2-port network to be reciprocal

The condition AD - BC = 1 for a two-port network implies that the network is a

The condition AD - BC = 1 for a two-port network implies that the network is a
