First some definition must be done:

Reciprocal Networks:
Two networks $ A$ and $ B$ are reciprocal to each other if their transimpedances have the following relation:

$\displaystyle Z_{mn,A} = Z_{nm,B}$ (5.1)

That means: Drive the current $ I$ into node $ n$ of circuit $ A$ and at node $ m$ the voltage $ I\cdot Z_{mn,A}$ appears. In circuit $ B$ it is just the way around.

Adjoint Networks:
Network $ A$ and network $ B$ are adjoint to each other if the following equation holds for their MNA matrices:

$\displaystyle [A]^T = [B]$ (5.2)
